-Implemented live like spell projectiles (ie mage bolts).

Browse Source 
-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

/*For mage 'Bolt' line and other various spells.
-This is mostly accurate for how the modern clients handle this effect.
-It was changed at some point to use an actual projectile as done here (opposed to a particle effect in classic)
-The projectile graphic appears to be that of 'Ball of Sunlight' ID 80648 and will be visible to anyone in SoF+
-There is no LOS check to prevent a bolt from being cast. If you don't have LOS your bolt simply goes into whatever barrier
and you lose your mana. If there is LOS the bolt will lock onto your target and the damage is applied when it hits the target.
-If your target moves the bolt moves with it in any direction or angle (consistent with other projectiles).
-The way this is written once a bolt is cast a timer checks the distance from the initial cast to the target repeatedly
and calculates at what predicted time the bolt should hit that target in client_process (therefore accounting for any target movement).
When bolt hits its predicted point the damage is then done to target.
Note: Projectile speed of 1 takes 3 seconds to go 100 distance units. Calculations are based on this constant.
Live Bolt speed: Projectile speed of X takes 5 seconds to go 300 distance units.
Pending Implementation: What this code can not do is prevent damage if the bolt hits a barrier after passing the initial LOS check
because the target has moved while the bolt is in motion. (it is rare to actual get this to occur on live in normal game play)
