FREESP and FREESPT 0.2

Introducing FREESPT a TSR version of FREESP. If you're using FREESPT you don't need to run FREESP (if you do want to use both install the TSR before running FREESP). The TSR will monitor for DOS interrupts that will call the disk space calculation and run its own faster method beforehand.

Minor update to FREESP doing better checking for empty command line arguments.

Tested under MS-DOS 6.22. Assembled using TASM 2.01.
