Two config variables added - disable_player_mice and uneducated_mice. The first, if enabled, prevents players from spawning as mice, and the second, if enabled, prevents mice from understanding human speech (which they now do my default)

universal_understand = 1 now allows player-controlled mobs to understand what everybody is saying without necessarily allowing them to talk back intelligibly. Mice have universal_understand = 1 by default.
