Bug Fixes (Cooldowns and Greying Items [Mail/Loot Bags])

Patched a couple of bugs to do with greying out items when opened (loot bags) and when items are attached to mail.
Also patched cooldowns as they weren't showing until the bags were opened and then closed.

Not sure the patches are the best, but they work.

Also half-heartedly attempted to patch the shuffle by doing the same thing as for the above (not sure it works and definitely not fixing the root of the problem).
