Random professions now selected for random characters, with "Survivor"
weighted heavily and expensive/flaw professions weighted less heavily.
Code cleanup.
Add pocketknife and (usually) matches back to the 0 cost flavor
professions, since they can be randomly selected now.  I skipped matches
on professions with weak melee weapons.  Also reduce otaku cost down to 1,
but reduced it's messenger bag to a purse (i.e., tailor that trades skill for
carrying capacity).  I think it got overlooked in the big profession
rework.
More interesting cost 0 prof items for bride/groom/clown/submissive.
Merge improved random profession selector.
