THIS COMMIT IS A HACK USED FOR TESTING. it switches in the UCF file some input and output pulse pins to allow for testing of optical repeater and map 1 optical channel to two TTL channels. DO NOT USE THIS BRANCH FOR PRODUCTION OR ANY OTHER PURPOSES. BRANCH WILL BE DELETED IF NO FURTHER TESTS ARE REQUIRED

added to the top entity the pcb version number coming from the pcb. connected this to conv-common-gw for hwvers register

Moved inverter channel logic inside conv-common-gw. This includes inv-channel LEDs. Also now using negative logic for all LEDs

Send front and rear pulse to conv-common-gw, not just the result of their OR operation. This is for implementing separate front and rear counters
