Upgrade to HLTS M3 Watchdog Screen and Oplev WD Path
While scouring the PR SUS screens and EPICs values to be sure they're up-to-date, I noticed that both the HLTS and HSTS overview screens (SUS_CUST_HSTS_OVERVIEW.adl and SUS_CUST_HLTS_OVERVIEW.adl) were still pointing to an old SUS_CUST_HXTS_M3_WD.adl screen which has some preliminary design of the optical lever portion of watchdog and was buggy in its parsing of the status bitword for PR3. Only PR3 has an optical lever, none of the HSTSs have one. I've now updated both overview screens to point to respective HLTS and HSTS M3 WD screens, SUS_CUST_HLTS_M3_WD.adl and SUS_CUST_HSTS_M3_WD.adl respectively. Their screen shots are attached.

The updated and new screens have been committed to the userapps repository, under
/opt/rtcds/userapps/release/sus/common/medm/hxts/
(Note I've also logged in and svn up'ed this directory, therefore updating the LLO screens for them since it's an noninvasive change, they also have no PR3 or SR3 optical lever yet, and haven't started using the lower stages of their HLTSs).

In addition, because the optical lever on PR3 doesn't exist yet, and the band-limiting filter bank on the RMS path wasn't visible/accessible/linked from the previous WD screens, they had remained empty until now. Similar to the OSEM Band-limiting filters (), I've filled in FM1 in the SUM bank ($(IFO):SUS-$(OPTIC)_M3_WD_OPLEV_BANDLIM_SUM) with the 10 Hz low pass, 
dcBandLim = zpk([],[10],1,"n") (foton design string)
and the P and Y paths ($(IFO):SUS-$(OPTIC)_M3_WD_OPLEV_BANDLIM_$(DOF)) with the 0.1 - 10 Hz band pass.
acBandLim = zpk([0;8192;-8192],[0.1;10;10],10.1002,"n") (foton design string)
Finally, for lack of experience, I've set the minimum SUM threshold to 5000 [ct] (based on half the typical light sum seen on the test mass optical lever), and the maximum RMS threshold also to 5000.
(These filters still need to be installed on LLOs HLTSs).
