AH-471 Spell is now a spear instead of sphere.

Increased spell speed, tried to do a little to the spawn of the explosion, but not working correctly. Still getting irregularly spawns.
AH-471 tuned flyforce.

To make the explosion sphere appear at the same place much more frequently.
Merge remote-tracking branch 'origin/master' into AH-471_TunaSpell
