hdl: Work on changing for V2 card 

The V2 card has the front-panel LEDs non-negated (the Schmitt-trigger inverters
have been removed) and has LEDs added for each inverter channel. The relevant
changes have been made in this respect as follows:
- changed signal names in UCF and top-level VHDL file
- changed polarity of pulse LED outputs to active-high
- added the inverter LED outputs
- added the inverter LEDs in the LED sequencing scheme for the LED test
