    Fix CheckPreconditionsAsync

commit 992407407a
Author: Hsu Still <341464@gmail.com>
Date:   Sat Sep 2 14:07:12 2017 +0800

    Add Async suffix to abstract Task methods

* Improve Boolean Property Summaries

Having the `CaseSensitiveCommands` property summary asking a question whenever Intellisense is invoked seems a bit nonessential instead of *properly* explaining what exactly it does. It would be better if instead, it stated it's use to be more comprehensible to the reader.

### Changes

- Edits the summaries of `CaseSensitiveCommands` and `ThrowOnError` to follow a more methodical convention for boolean property summaries (`Determines whether X ...` rather than `Should X be ... ?`).

This is just a small change to improve upon the current documentation, so it shouldn't conflict with anything.

* "DefaultRunMode should also be "Gets or sets blah blah blah" to be consistent."

* Add BaseDiscordClient. Add various missing RequestOptions args.

DiscordSocketClient and DiscordShardedClient's shared members now exist in this abstract class.

* Add ShardReady event.

* Style consistency. Remove extraneous overloads.

Remove extraneous overloads.

* Add BaseSocketClient#DownloadUsersAsync().

Style cleanups.

* Add ShardLatencyUpdated event.

Style cleanup.

* Hook LatencyUpdated for ShardedClient.

* Begone whitespace.

* I'm good at this, I swear. >_>

* Add back DiscordShardedClient.UserPresenceUpdated

* Add ObsoleteAttribute

* Removing the UserPresenceUpdated event.

Also changes target to NetStandard1.3

* Partial fix of #810, addresses critical connection issues.

* Implement fix for REST.

* Implement fix on RestChannel.

* Remove extra AddField overload in EmbedBuilder

* Remove AddInlineField()

* Add GetReactionUsersAsync(IEmote) overload

Resolves #730

* Remove obsolete GetReactionUsersAsync(string) overload

* Add NullableTypeReader.

Primitives now also load a NullableTypeReader<T> and any value types that get a typereader added will also have a NullableTypeReader<T> added for it.

* Remove unnecessary null check.

* Added docstrings.

* Changed Guild#DefaultChannel to resolve the first accessible channel

Resolves #776

This change is inline with hammerandchisel/discord-api-docs#329

RestGuild#DefaultChannelId is now obsolete and will throw a
NotSupportedException.

* RestGuild#DefaultChannelId will fall back to the guild ID

Adding an exception here would be a breaking change, so this was agreed
to fall back to the previous behavior, which would just return the guild
ID.

IChannel.IsNsfw will now return false when being used on any channel
that is not an ITextChannel. When being used on an ITextChannel, this
will now account for the API flag, and fall back to the channel name.

(this is gross design, thanks discord)

* Fix CreateGuildAsync not doing anything with the input stream for the guild icon.

Also fixes an issue with potential stream types that throw a NotSupportedException when checking its properties. [Apparently, they exist.](https://github.com/dotnet/corefx/blob/master/src/System.Net.Http.WinHttpHandler/src/System/Net/Http/WinHttpResponseStream.cs)

* Merged with old method

* Removed duplicate decl
