U-HEPHAESTUS\bonachea:
	- fix duplicate QTip:Release() calls
	Previously the addon was sometimes calling QTip:Release() multiple
	times on the same acquire_tip handle between QTip:Acquire() calls.
	Second and subsequent Release calls on the same handle are
	invalid and have a high probability of corrupting the tooltips of
	other unrelated addons using LibQTip.
