Merge branch 'terencehill/ons_spawn_patch' into 'master'

Onslaught spawn point selection improvement

Onslaught, control point selection through the radar: increase chances that a spawnpoint can be found even if there's little room around the control point (now a spawnpoint near the control point in the middle of runningmanctf can always be found, unlike before)

EDIT: actually even with my patch sometimes a spawnpoint near the control point in the middle of runningmanctf can't be found, I'd say there's a 10%-20% chance, yet much better then before (100%)
