Maps and cleaned up what each computer could do

made 5 more maps, some might be unstable...
made it so you can't really scroll any more, and restricted comp 1 and 3
to just space bar and left the rest with comp 2
sends scores from comp 2
should be pretty solid

fixed the problem with the 3 computers having different tower falls and
being unsynced, by calculating score only on comp 2 since it is the one
the players can see and sending it to the clients
fixed other small bugs
played the music Tanczos gave me, but kept a small snippet of the
drumline for the winning/losing sequence (can remove if unsatisfactory)
commented out all commands that the client or server comps shouldn't be
able to access
isolated camera shake to only the screen the cannon is in, so comp 2
never shakes, (can restore to what it was before if unsatisfactory)
loads plane if any of the map keys are pressed but only for the first
time
got rid of map 9 because it was too easy and fell down without hitting
it sometimes, just made key 9 load map0
woops
