Crash detect, chat channels, fixed mcchat, improvements

[NorbiPeti]

• Crash detect, will post if the server shut down unexpectedly
• When announcing a Reddit post, it will use Discord names whenever possible (although Reddit users aren't saved separately yet, so it doesn't work)
• It should print "full house" when all developers get online
• Added chat channel support
• Bot commands can be in any case
• Fixed ProtocolLib error on fake player join/leave by leaving it out of the fun
• It'll automatically "kick" fake players on disable
• Private pins won't be announced in chat
• Player names are clickable and they link to the user's (soon to be actually implemeted) profile using either the Minecraft or Discord ID
• Chat rooms implemented (probably)
• Fixed fake user name, some plugins depend on MC name - Players will need to relog into mcchat if their name changed
• Fixed join-while-mcchat in ButtonCore
• Fixed Discord->MC messages showing up in inccorect places on Discord
• Fixed chat channel feedback
• Other fixes
