Refactor fuzzy help and clean up help command (#2122)
What's changed:
- Fixed issues mentioned on #2031
- Fuzzy help displays more like help manual
- Fuzzy help is easier and more flexible to use
- Fuzzy help string-matching ratio lowered to 80
- Help formatter is more extendable
- Help command has been optimized, cleaned up and better incorporates fuzzy help
- Added async_filter and async_enumerate utility functions because I was using them for this PR, then no longer needed them, but decided they might be useful anyway.
- Added `Context.me` property which is a shortcut to `Context.guild.me` or `Context.bot.user`, depending on the channel type.
