Automatic VoiceChannel handler for dynamic channels

[DerDomee]

This feature branch adds a handler for automatic dynamic voice channels on the server. It is inspired by many other bots that already have this functionality. I add it in the most simple way without discord.ctx, but with my own semi-context system.

Missing Features to this point:

VoiceChat Commands, allowing the channel owner to

• toggle visibility Done in 0d2e020be17ba678ff7a89275391af199908d82f
• set channel name Done in 0d2e020be17ba678ff7a89275391af199908d82f
• transferring ownership of channel
• invite new people to private channel
• kick specific members out of the channel
• manually close this channel and kick every member

Newest commit 3a33cda7e21bb335c3ee11548c458dca9a5a2801 adds detailed comments containing the requirements for each function that is related to voice channels. Awaiting approval to implement everything like this.

I assume updating the voice-/text-channels more than 2 times lets me crash into the discord rate limit. Needs further testing about the timings. But maybe this whole rate-limit talking is just crap and instead I am boosted, not spotting an obvious error.

Problem occurs when toggling channel visibility (thats what im currently implementing): I can toggle the visibility two times. So in both directions the toggle works perfectly. But the third toggle doesnt succeed and the bot seems to be unable to see/edit/delete/do anything regarding the channels. Changing the role's name seems to work every time though.

I limited the usage of voice toggle and voice name to a total of 2 times per dynamic channel. This prevents the weird error that stops the bot from interacting with the dynamic channel after a third channel edit. This is only a hacky workaround that might be fixable. But I dont know how to fix it yet. Help needed.
