Fix many bugs with the Symbols menu (when run with -d argument).
The Symbols menu is now fully useable.
A much more complete dsy file is included, called combined.dsy.
Generate the Symbols then use the combined.dsy file to identify far more functions.
Add "Load bad map file" option for map files on disc that don't quite match.
Currently it is very simple and naive, but filters out most of the bad matches.
