SMcNeill 6e01fc8dce Altered string compare routines (<,<=,>,>=) so they don't give false results with CHR$(0).
Added new _STRCMP and _STRICMP commands for quick string comparisons.
Cleaned up QB64 to finish removing the QUI (quick user insert) code and folders.
Altered UCASE and LCASE routines to be faster in some situations for us.
