More work on the CheatManager. Stella now reads from a user-specific
'stella.cht' file, where each line/record consists of a ROM md5sum and a comma-separated list of cheats. Each cheat is specified as a colon-separated string, defined as "NAME:CODE:ENABLE". git-svn-id: svn://svn.code.sf.net/p/stella/code/trunk@895 8b62c5a3-ac7e-4cc8-8f21-d9a121418aba
