No longer mess with sys.argv (messing with system variables is a bad thing, right), use argv to determine pathname of executeable as sys.path[0] is just the first component of the path. also all database errors except MySQL reporting "Access Denied" should now crash FPDB, so someone can fill those into Exceptions, and into the fpdb_db and the fpdb files.

Process: get crash info, add exception info to Exceptions.py, catch generic database exception in fpdb_db.py (around the connect line), throw correct Fpdb exception, then catch it in fpdb.py and do the appropriate thing on the GUI end.
