rebalance some brawler & skirmisher stuff

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 :/

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

Random artifacts now have a 25% to pick a non-physical damtype of one of their themes
Improved actor tooltip
Improved/changed many egos
