Checking in WIP for DiStella integration. The disassembly is now shown in
the RomListWidget instead of being printed to the terminal. There are still graphical glitches with this, but for a first pass, it's nice to see actual Distella output in Stella. Partially working 'disasm' command from the PromptWidget. Currently, it only disassembles cart address space (aka, 0x1000 or above). Removed the old disassembly code from CartDebug. Still TODO is fix the label stuff, both in getting DiStella to use it, and adding/removing labels. This is greatly reduced now that we only have to worry about user labels. git-svn-id: svn://svn.code.sf.net/p/stella/code/trunk@1934 8b62c5a3-ac7e-4cc8-8f21-d9a121418aba
