Summary: new respawn algorithm

Initial Comment:
The red vs. green CTF format has become more and more
popular lately. With both teams at 4 players, there are
a lot of bad, i.e. unsafe respawns. It's more
complicated than in the free for all case, because the
area allowed for espawning is much smaller in CTF. So,
very often the respawn algorithm cannot find a place
which it considers safe. In tht case, it just uses a
random point.

This patch chages that behaviour. The algorithm will
still stop looking for a good point as soon as it found
a spot which it considers safe (i.e. minimum distance
to all enemy tanks and will not be hit by a shot in
<2s). If it cannot find a safe spot in 1000 tries, it
will now use the best of the unsafe spots. The best
spot is that, which violated the constraints by the
smallest amount.

Some quick tests seems to indicate that the patch
indeed seems to work quite good. There are at least two
scenarios which can still happen (old version had the
same problems):

1) Might get hit by a ricohet shot immediately after
respawn. This can happen, becuase for the shot
collision test, only a simple projection is done.
Actually, it doesn't consider buildings at all, thus a
shot is seen as a threat even when a building would
block it.

2) You migh trespawn right in front of a friendly tank.
This can be dangoerus, if your friend was just about to
fire a shot, you respawn, he clicks - you're dead.

maybe as an option you should always respawn on ctf base?
