Combat display tweaks
- Comparing gloves to gauntlets resulted in bogus previously due to a peculiar asymmetry in the calculations. Now it take sthe right defaults!
- "Advanced weapon stats" game option now also changes the comparison, for viewing pleasure and profit.
- Speed for unarmed stuff displays their actual speed for Brawlers now.
- Speed comparison now works. Had to change how compare_fields works but nothing else uses that fashion in vanilla and the old way made little sense (to me at least) anyway.
