Skill upgrade, more commands, fixes (#21)

* add BuyWallpaper

* added partial stage clear info handling, no longer fails get check

the creation of the clear info still has imperfections, so I've left it disabled for now. no point in letting it clutter the DB until the info is at least accurate in the UI.

* unfinished CP calculation stuff

still need to impl other tables (equipment), need a better way to capture outputs and compare them to retail, not really worth the excess work currently since CP calc isn't used anywhere critical right now

* AddItem command

* AddCharacter command

* finishalltutorials command

* addallmaterials command

also load the material items table

* skill upgrade impl

* update README

* potential fix for bodies not being removed properly on limit breaks and core upgrades

the client seems to be smart enough to deal with zero count item entries, so there's no real reason to remove zero count item entries from the DB

* check to make sure we have the character before adding a body

* use CreateWholeUserDataFromDbUser instead of doing a manual copy
