Bug fix: hardware version register address and offset were incorrect. Fix should allow now for reading of correct address on pts

HACK: the pts reads the hwversion as 0.0 even though it should be 4.0. suspect bug in pts gw. to be fixed

modified path to pts files, as home directory on pts computer is no longer pts but pts-administrator

Renamed front panel leds to reflect n4egative logic. Added support for reading pcb version number from pcb. removed separate process and sequence to test inverter led's

Also removed unnecessary SVG files
