Implemented live like spell projectiles (ie mage bolts).

-See function in spells.cpp for more info on bolt behavior.
-This works reasonably well, but still room for improvements.
-Rules are for setting what item id is used for the projectile
since live uses an item id from SOF+ I added alternate item graphic
for titanium clients.
-Note: Max number of projectiles (set at 10) is a made up value in most
situations it would be nearly impossible to have more than 3 bolts
in the air at the same time. This values gives enough wiggle room that no
server should have an issue though.
-Small fix to SE_CompleteHeal
