This adds:
* CategoryChannel, which represents a category
* Guild.by_category() which traverses the channels grouping by category
* Guild.categories to get a list of categories
* abc.GuildChannel.category to get the category a channel belongs to
* sync_permissions keyword argument to abc.GuildChannel.edit to sync
permissions with a pre-existing or new category
* category keyword argument to abc.GuildChannel.edit to move a channel
to a category
In Discord, if the @everyone role has an explicit allow but a later
role has an explicit deny, the permission is denied rather than allowed
despite the fact that on Discord, allows have a higher priority than
denies.
This is because the @everyone role is supposed to be the first role to
be applied, while the rest could be applied in an aggregate fashion.
Fixes#630.
This now sort of respects "Awaiting Endpoint..." waiting. I haven't
actually tested out this case since it's hard to get it. However this
new code does work with the regular connection flow.
This is a complete redesign of the old voice code.
A list of major changes is as follows:
* The voice websocket will now automatically reconnect with
exponential back-off just like the regular Client does.
* Removal of the stream player concept.
* Audio now gracefully pauses and resumes when a disconnect is found.
* Introduce a discord.AudioSource concept to abstract streams
* Flatten previous stream player functionality with the
VoiceClient, e.g. player.stop() is now voice_client.stop()
* With the above re-coupling this means you no longer have to
store players anywhere.
* The after function now requires a single parameter, the error,
if any existed. This will typically be None.
A lot of this design is experimental.
This is a breaking change. No longer does Messageable.send have a
filename keyword argument, instead this is all handled through the
discord.File model. To upload many files you must specify a list
of discord.File objects.
This is a breaking change. Move these two to TextChannel since the
other things that implement Messageable cannot reliably do bulk delete
actions in their respective channels.
