some updates needed

A bug in the GetAvailableBalance() method in PyCryptsy caused breakage. Cryptsy returns coin abbreviations in all-uppercase.

Also, all altcoins that are supported by CryptoSwitcher and are tradable on Cryptsy now have sell* options down toward the bottom.

I also fixed .gitignore to keep DEADJOE files out. (They're created when something unexpectedly kills my editor, like a disconnect.)
