Discord allows the slow mode to be up to 6 hours.

* Set the @everyone IRole for @everyone and @here tags

Adds support for setting the IRole corresponding to @everyone or @here in a the tags of a message. Previously this would only set the TagType, but leave the value as null.

This does not distinguish between @everyone and @here, as that's done using TagType. The values of both will be the same.

This issue was suggested by @TheCasino

Fix #1270

Adds the AuthorId property to MessageDeleteAuditLogData, which is set

    Add the CreatorId property to GuildEmote implementation

commit e0eb94d44c
Author: Chris Johnston <chris@thejohnstons.net>
Date:   Fri Dec 14 23:41:54 2018 -0800

    Update the Emoji API model to add User? attribute

* feature: add DiscordSocketRestClient

this resolves #803.

Users can access a DiscordSocketRestClient from the new
`DiscordSocketClient.Rest` property.

DiscordSocketRestClient is a wrapper over DiscordRestClient with certain
state-modifying methods, such as Login/Logout disabled, to prevent users
from breaking the client state.

DiscordSocketRestClient uses the same API client as the
DiscordSocketClient, allowing for shared ratelimiting - meaning users
can now force HTTP requests without needing to wory about running into
429s.

* fix: disallow users from bypassing shadowed login

* Move invites-related methods from IGuildChannel to INestedChannel

* Add missing implementation

...because I somehow forgot it the first time around

* Initial set of dispose implementations

Not handled yet:
- Discord.Net.Websocket/Entities/SocketGuild
- Discord.Net.Tests

* Refactor DiscordSocketClient init into ctor

This way we remove an IDisposableAnalyzer warning for not disposing
the client when we set the client variable.

* Dispose of clients when disposing sharded client

* Finish implementing IDisposable where appropriate

I opted to use NoWarn in the Tests project as it wasn't really necessary
considering that our tests only run once

* Tweak samples after feedback

* Added ability to specify position when creating a channel

* Adjusted categories to include guildproperties and allow specifying position when creating channel categories

* fixed unimplemented methods (for CreateCategoryChannelAsync) and added appropriate documentation

* Add AddGuildMember Oauth endpoint support

* Concat RoleIds if already exists.

* Use local ids variable.

* Remove RpcException

* Move RestConnection to Discord.Net.Rest

* Remove RpcVirtualMessageChannel

* Move REST objects to Discord.Net.Rest

* Fix Discord.Rest namespace

* Add maxage check & improve maxage parameter check

* Change InvalidOperation to ArgumentOoR

* Remove HasValue check
...since it does it implicitly already.

* Add parameter names & better wording for invite OoR

* Move maxAge check to DiscordRestApiClient for consistency

* fix: strip trailing slash from ratelimit bucket IDs

This resolves #1125.

fixes a bug where some ratelimit buckets would include a trailing slash,
while others wouldn't; this would cause them to be treated as separate
ratelimits, even though they are the same

ideally this fix should change the ratelimit generator, but that code is
pretty complicated and this was an easier fix that seems less likely to
break things in the future.

tested against normal bot function, all routes are assigned the proper
buckets from my testing, so this should be good to go.

it's fine

* fix: ensure add/del rxn ends up in the same bucket

this was the name change i always wanted

This adds the following property to ITextChannel
- SlowMode (int)

The SlowMode field defines the time in seconds users must wait between
sending messages; if zero, slow-mode is disabled.

Bots are not affected by slow-mode, and as such, no changes need to be
made to the REST client's internal ratelimiting. This is strictly a
read/write cosmetic property for bots.

* Fix swapped parameters in ArgumentException and ArgumentNullException cstrs

The constructors of ArgumentException and ArgumentNullException are inconsistent with each other, which results in their parameters being swapped here and there.

* Change all Select(... as ...) to OfType

* Add token validation to BaseDiscordClient#LoginAsync

Adds a TokenUtils class which is used to validate that tokens are correct

* Revert changes to DiscordRestApiClient

* Add Unit tests to the TokenUtils class, fix a logic error that was caught by those tests

* Allow for API to throw exceptions

Moves the validation of tokens to be inside of LoginInternalAsync, and writes a Warning to the console when the supplied tokens are invalid

Should fix issues in audit logs when deserializing overwrites and
similar types which we use a custom contract resolver for.

* Mark guild as optional for invite

* Mark partial InviteMetadata members as Optional<T>

* Some of them aren't sent when requesting through the general GET invite endpoint

* Remove GetInviteParams

* It was kinda stupid in the first place, might as well always get the count instead of having to ask the user whether they want the two fields filled or not.

* Add ChannelType property

* Add vanity invite support

* ConnectAsync(bool external) API implemented

This allows developers to handle the AudioClient externally (for example with Lavalink)

* Modify ConnectAsync API and add DisconnectAsync to IAudioChannel

* Update summary message on IAudioChannel.DisconnectAsync()

* Review changes:
- Fix `if (!external)` styling
- Remove unecessary ConnectAsync overload

* SocketVoiceChannel overload update

* Update IAudioChannel.ConnectAsync()
- Remove ConfigAction from parameters
- Add SelfDeafen/SelfMute to parameters

* Remove SocketVoiceChannel.ConnectAsync() default params (Inherit)

Closes #1074

This code was not referenced anywhere in the active codebase.

Discord no longer treats channels prefixed with 'nsfw' as NSFW,
so we no longer need to have this check.

All of this should improve docs.
