fixes a bunch of blacksmithing stuff

the blacksmithing skill is now actually dwarfy instead of not because of a typo

picking up how ingots without gloves is now not a better decision than picking them up with non-heatresistant gloves.

you can't interact with anvils while they are already being worked to prevent issues.

Also fixes associative skill level code a tiny bit.
