Fix vanilla spell cast and use-item packet formats for Turtle/Classic

Browse source 
SpellCastTargets target mask is uint16 in vanilla 1.12.x, not uint32
like WotLK. The 2 extra bytes corrupted every spell packet. Also add
classic CMSG_USE_ITEM builder (bag+slot+spellIndex+targets only, no
spellId/itemGuid/glyphIndex/castFlags fields that WotLK added).
