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.
The reason it is 2 is so you can use the 2 key as the shortcut key. But I can change it if you don't think it is worth it.
