Wraith

Adds boss monster in the likes of the Jabberwock and the Sludge crawler
Removed sundeath from wraiths
Fixed the missing value in savegame.h
Merge branch 'master' into Wraith
Rookie errors

Fixes three errors that I found
Tweaks the Spawn and behavior of the Wraith

It now spawns in the cult cabin first floor, also I gave it sundeath and
removed its ability to follow you so you could kill it by opening all
the windows of the main room to let light in
Remove needless redundancy
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.
Creates  the medieval content pack
Forgot to rename a file
Two things I forgot
Moved everything medieval

Every single thing
Small fixes
Moved content

Returned tonfas to vanilla and moved repeating crossbows into the mod
Moved the cudgel back to vanilla
Mods can now have their own lua files.

Furthermore, added game.dofile function, which executes a lua file from the current mod directory.
Fixed unused parameter warnings.
