Added different names for attach and equip

+ moved implementation of AEquip to .cpp
Fixed issue with Cranial Plating.

Issue
	attach then equip: plating will give bonus to both creatures
Fix
	Changed "attach" to "retarget target(creature|mybattlefield)"
	as this doesnot admit this bug
	Attach should become deprecated in future
Merge pull request #555 from WagicProject/fix-cranial-plating
