Changes and Fixes for unarmed_attacks kick and stomp

Same as #7485, still without the reimplementation of the magboot stomp.
These commits left here are fixes and rebalances that should be merged before the dev-freeze branch gets merged.
Please try to name your procs informatively. unarmed_damage() does not really tell you anything about the function of the proc. get_unarmed_damage() would be better.
