Improved ghast combat

* ghast fireballs can now hit the shooter (used to just fly through)
* improved ghast aim
* increased ghast fireball lifetime
* mob projectile lifetime is now counted in seconds (was in ticks)
* improved variable naming
* improved default mob projectile deflecting (applies to ghast fireball)
