Updated to 1.0, bugfixes, and dropoff chans

Updated the base TSSync to 1.0.0.0.
Fixed the issue where players in pickup channels would be force moved to
staging channels when they weren't in game.
Added dropoff channel support so that staging channels are only used for
intermission/round-change discussions.  !tslobby will still take you
back to the staging channel, not the dropoff channel.
