The data from last week's calibration of PCAL EX was corrupted by HWINJ's still being on -- which were understandably missed because the new HWINJ infrastructure (see LHO aLOG 46407) didn't get propagated to (and admittedly never was on) the PCAL "excitations" screen, and the remaining HWINJ CTRL screens were white with vestigial channels.

As such, I've 
- Removed all calls to old HWINJ screens from the site map
- Added the HWINJ path to the PCAL EXC screen (with a link back to the now one-and-only HWINJ CTRL screen.)

Now all excitation paths to the PCAL DACs are shown on this excitation screen.

While I was add it, I cleaned up the screen to make it more clear:
- Added an end station label at the top, so as to not get confused when both end station screens are open
- Changed the OSC_SUM_MATRIX link button to a blinky-light matrix, so it's obvious from the EXC screen level which lines are requested to be ON
- R-arranged the addition of the DARM and SWEPT SINE path, to better reflect how they're added and sent out to the DAC in the front-end code.

I did hit one "hitch" though -- the visualization of the "$(IFO):CAL-INJ_END_SW" channel which controls to which end-station the now-corner-station-generated HWINJ signal goes is buggy, because I can't figure out how to get a common MEDM screen to both end stations (which are otherwise riddled with macro substitutions to differentiate labels and channels) to show the correct operation of the channel at each end station.
This can go on the low-priority list to fix.

The updated sitemap and common excitation screen have been committed to:
