Training dummy revision

[Sol Lignum]

While they can't really teach much besides attacking, there're few things that would be nice to see:

First of all,
Attacking with diffirent weapons or under certain condition, should raise corresponding stats, besides attack alone. Hitting dummy with light weapons should give a character some idea about dexterity, and clubbing them should raise strenght.

Second, not completely a dummy thing, but this idea is brewing in my head for a long time, and kind of relevant,
Sparring system. Would be great to see more experienced characters teaching rookies how to fight in such manner, maybe raising their skills up to 1\2 of what teacher knows, cuz they don't want to beat newbie to death. Equal fighters could benefit from sparring as well, just at the same rate, that could be, again, half or quarter from combat leveling, since, again, friendly sparring.

And last but not least,
Training dummies are expensive as hell, players should not be faced with a choice between building a large structure or 3 dummies.
