Add a help screen showing the message slash commands and keyboard shortcuts

[nikolaiwarner]

The keyboard shortcuts and special message commands such as "/nick" or "/emote" are unknown to users. We should have a help screen in the app listing those features.

Maybe this can go next to emoji picker for now?

@nikolaiwarner let's continue working under this issue for including slash commands from the cli. Current list of commands from the cabal README are:

/channels 
   display channels you can join
/names
   display a list of the people currently online 
/join <channel> 
   join a channel
/j
   alias for /join
/nick <new nick>
   pick a new username
/n
   alias for /nick
/emote <some text> 
   write an old-school text emote
/me
   alias for /emote
/clear
   clear the current backlog
/help
    display a help message of the current commands
/quit
   exit cabal
