Changes

Protocol.c: Exclude players in spec team from dist checks

Spectator players cant really move or change their
positions. So the dist checks would fail for them.

Thus rendering some "funny" bugs
 (commit: 45efcad)

Packets.c: Send reloading packets as they should be

Previously reloading packets would not be
sent to the player that reloaded causing
voxlap to go bonkers which is less then ideal ofc.

Now the indicator that someone started reloading
is sent to everyone except reloading player
and then actual ammo reload is sent to ONLY reloading
player.

Server: Tiny fixes

Map.c: initialize the arrays with 0s
so valgrind doesnt complains

Rest is just few fixes around reloading logic
