Fix for issue #3 and #5: Enums, RPCs, Player Counts

Fix for issue #3 and issue #5: Updated parameters on "TheEnd" call to
cast the enum type as an int before the RPC call; I did some Googling
and it seems like you can't pass enums in this way and this is the best
solution to resolve the error. I also updated the counter (via a
decrement) in the ServerC GUI. If you accept this pull request then you
can close these two bugs in the issues list.
Merge pull request #11 from mattm401/master

Fixes #3 and #5 - convert enum to int when calling RPC a decrement players by 1.
