- Fixed itemskill variable being cleared before parsing the skill, this causes auto-casted teleport to fail to skip the skill menu. It is now cleared on castend_pos/id directly.

- The item skill/lv variables now use 0 as default to signal they aren't being used (instead of -1)
- Skills with state 'move_enable' will now do a "walk path" check between target cell/object and caster instead of a "shoot path" check, this would fix skills like snap or charge from letting you "teleport" across pits.
- Fixed a possible double map_addblock when hatching a pet egg right before going through a warp.

+	* Fixed itemskill variable being cleared before parsing the skill, this

+	  causes auto-casted teleport to fail to skip the skill menu. It is now

+	  cleared on castend_pos/id directly. [Skotlex]

+	* Skills with state 'move_enable' will now do a "walk path" check between

+	  target cell/object and caster instead of a "shoot path" check, this would

+	  fix skills like snap or charge from letting you "teleport" across pits.

+	  [Skotlex]

 	* Raised the amount of skills that can stack on a single cell before the

 	  "in-area/out-area" detection code breaks to 24 (from 8) [Skotlex]

 	* Fixed a crash in clif_SkillInfoBlock if the passed player already
