* Parse double for X-Reset-After instead of float, needs more precision

Float did not contain enough precision to store the millisecond unix
time value, which resulted in the second and millisecond values being
slightly off.

This can be easily tested using:

```cs
> DateTimeOffset.FromUnixTimeMilliseconds((long)(1470173022.123f *
1000)).Millisecond
160 // wrong

> DateTimeOffset.FromUnixTimeMilliseconds((long)(1470173022.123 *
1000)).Millisecond
123 // correct
```

* Parse RateLimit-Reset using an IFormatProvider

* State NumberStyle and use CultureInfo.InvariantCulture for any parsing

This updates most occurances in the code where a Parse or TryParse method was used to explicitly state the NumberStyle, and to use CultureInfo.InvariantCulture.
CultureInfo was used over NumberInfo, as it also works on DateTime parsing too.

* Use default format spec in Commands

While it might be more proper to refer to a voice state as composing
a stream (i.e., the IVoiceState is a Stream), this property is ported
up most often to actual user entities. It makes more sense to
communicate that the user is streaming, rather than stating that the
user itself is a stream.

This is also more gramatically consistent with the other voice state
properties (e.g., IsMuted). Movement from noun-form to participle-form
remains inline with the past-participle form used on the other
properties.

* Add self_stream voice state property

Adds the self_stream property which is set true when a user is streaming a video to a voice channel

* use flags for selfstream state instead of its own prop

* Implement Client Status Support

Adds support for using the client_status as sent as part of the Presence model. This value can be used to determine if a user is active on the native desktop app, the mobile app, or the website.

* lint: whitespace in IPresence

* Remove breaking change to IPresence interface with a note for 2.1

* update comment to not reference 2.1

* re-add interface break to IPresence

* add example payload for client_status

* use inline declaration for Enum.TryParse

unsure if there would be a better name for this enum, given it's inverted nature, open for suggestions

* add method for getting vanity image from CDN

* make the size of GetGuildVanityUrl optional

* lint: remove commented out code from prev commit

* add a None flag to SystemChannelMessage enum

* implement the new modify guild params

* implement additional model properties in IGuild types

* implement GuildMember PremiumSince

* docs: reword size param explanation

* add extension methods that make it easier to check the SystemChannelMessage flags for end users

because the flag is inverted, this ideally should make it easier for the user. it may also be useful to do something similar for modifying this property

* docs: correct typo from copy-paste

* add the premium_subscription_count property

* fix vanity url code and banner switchup

a mistake was made somewhere, that's all I know for sure

* clarify remark on inverted logic for system channel flags

* incomplete implementation of interfaces

* Add implementation of activity flags, and extension method to check flag

* remove usings that were not required

* clean up files and add documentation where missing

* remove unused usings

* Add remark saying that premium_type info may be inaccessible to bots

it seems that this information can not be accessed by any user,
and may require the identity oauth scope

* Add locale property to the user model

adds the locale property to the user model, which appears not to be
specified for bots

* rename ActivityFlags

* Add incomplete xmldoc to ActivityFlag

Added xmldoc to the ActivityFlag type, excluded flags that i was unsure about

* rename the UserFlags file

* Rename Flag enum types to use Properties suffix

* Expose the details field in the Game model

* update Activity extension methods to support Details field

* Use inherited Details implementation in RichGame

* lint: remove commented out code from debugging

* Fix issue in previous commit

* Move oauth-only user fields to SelfUser classes

Moves the implementation of the Flags, PremiumType, and Locale user fields to ISelfUser classes. In testing, it seemed that normal bot accounts did not have this information supplied to them. When tested with a Bearer token in the Rest client, these fields are set.

* remove old HypeSquadEvents flag that appears to have been replaced with the new HypeSquad flags

* Feature: Disconnect users from voice channels

Updates GuildUserProperties to allow for setting either Channel or ChannelId to null, which will disconnect users from voice channels.

The type of ChannelId has been updated from a ulong to ulong?, which matches the latest api documentation.

* docs: update xmldoc wording

* breaking workaround, revert ChannelId to ulong

This is a workaround to prevent this PR from being a breaking
change. Reverts the type of GuildUserProperties#ChannelId to a
ulong from a ulong?. Guild Users may no longer be kicked by
setting this property to null, but setting
GuildUserProperties#Channel should still work.
