add some helper methods to Location structure. thx to cyberium
use WorldLocation in SpellCastTarget
allow use DB table coordinates for spell with Target 46 (mostly TARGET_SCRIPT_COORDINATES, TARGET_NONE). allow make DB defined teleports/summon points.
spells example - 64014 (ulduar regular teleport), 707181 (ICC regular teleport), many spells in WG.
(requires "use WorldLocation in SpellCastTarget")
need test - but usable only after fill DB table by real coords.
