I've made several changes to the TwinCAT code and medm screens for ALS friday and this morning.  The most important thing is that I added the slow feedback from the COMM PLL contrl signal to the IMC VCO.  At the bottom of the COMM PLL screen now there is a section for the Sow feedback, if this is running it replaces the IMC-VCO_SETFREQUENCYOFFSET with an error signal that cancels the error signal from the frequency comparator and replaces it with the PLL control signal, multiplied by a gain.  The gain is currently 10000Hz/V.  This also checks to see if the arm cavity is locked, if the SHG status is OK and if the beatnote stength is above some minimum, and will stop the feedback if there are error conditions.

This seems to be working well as long as the arm cavity has the slow feedback to the top mass active. 

Other updates were adding an error conition to the end station laser locking pll for the noise eater oscillation, fixing the corner state machine, and adding an option to the PDH autolocker to allow it to control the second boost.  medm screens updated were mostly in ALS, except for ISC_CUST_DUAL_PFD.adl
