Users can now create a new room directly in Gomuks

Added the ability to create a room from within gomuks using the now
`/create` command. This comman takes the room name followed by the
alias. Room name may contain spaces but the alias may not as per the
Matrix alias conventions.

Also update `/help` to include the new command.
