Attempting to simplify Meteor Code

Since Meteor is a lag-inducing gamemode by design, I've done my best to
try to minimize said lag :

- No prob check in the Meteor process(). The random number generator
(which runs constantly) shouldn't cause too much lag. SHOULDN'T
- Individual meteors now only attempt to spawn three consecutive times
- Simplified exceptions
- Removed delay when pushing meteors at spawn
- Commented out code fired at every meteor Move() proc that attempted to
ignite the turf

Small tweaks have been done to the rest of the gamemode, mostly to make
it a little bit harder. You can still sail smoothly by hiding in the
Bridge, it shouldn't be
