Nerfed the damage of low level rogues and crystals

Buffed iron & steel weapons to make melee/archery start more fun
Buffed Healing Infusion

Big movement speed effects like lightning speed, movement infusion, .. now display a fractional effect to see how close to end they are

reverted unarmed mastery change because, well it did nothing; masteries dont work that way :/

Set definitions set_list, on_set_complete, and on_set_broken can now be tables of several different actions to take for different set ids
Made set_list able to be a function
Sets can now check against a specific inventory slot

revert acidic skin; if oozemancer melee protection needs reducing we can do better than bland'ing a talent :)

to be much tested, most work by housepet
