Breast update

See merge request Ed86/rjw!26

Added udders, removed breasts from animals that shouldn't have them (mostly reptiles and birds, few amphibians, etc). 

Bug fixes

See merge request Ed86/rjw!25

No need to check for 'CurJob == null'. Can't get to jobgiver if the pawn isn't looking for a new job, unless triggered from console. And blocking that out makes things hard to test.
