Couple of fixes and a new feature for bank/GB (#25)

* Exclude crafting spells using Fel Blood

Updated cost calculation to exclude spells using Fel Blood in crafting.

* Epoch lua error fix

* Slow mail loot when low FPS to avoid double looting

* Allowing withdrawing items from bank/GB using "AH shortfall" to withdraw based on post cap and now ALSO minPrice of those items has to be above current DBMinBuyout.

* Fixing an infinite loop bug with invalid custom price of Default Craft Value Method
