Slow controls software update

The tidal code has been changed by adding a delay trigger to the red lock trigger and by requiring a lock condition to go into the red lock state. This should avoid the problem where the tidal state machine keeps switching states upon cavity flashes after a lock loss.

Prepared a change in the LSC/IMC model to enable the common tidal from MC_F using a switch after the MC_F filter module. This way we can switch on the common tidal feedback independently when the tidal state machine is in the transition state.

New slow controls code was loaded into the remaining EtherCAT systems to support automatic screen generation.

A new feature was added to the auxiliary library to allow momentary switching of its binary outputs. This has been implemented for the ESD power on/off channel to avoid the problem with the 4 second auto-reset when the channel was left in the high state by mistake. A high transition will now generate a one second long pulse which returns to low automatically.
