changes to random doubles item generation

- added charti & occa for 4x weaknesses
- made yache only for 4x weaknesses
- made it so you cant have fake out & sheer force (9-21-14)
- changed it so shuca berry and chople berry won't be added to
immunities
- unburden mons only have normal gem if they have fake out as opposed to
any normal attacking move
- made life orb more common over expert belt

fixed error in shuca generation

typoed, but fixed it so now it should only give shuca berry to pokemon
without a ground immunity

fixed broken indentation

fixed issues pointed out by slayer95

should have fixed the indentation and edited the  immunity check
