Control Room OSEM overview screens

The OSEM overview screen that has been running on the top leftmost monitor in the control room has been showing the raw OSEM signals (e.g., H1:SUS-MC1_M1_OSEMINF_T1_INMON) before normalization to ±15000 counts and conversion to microns. This makes it harder to see anomalous offsets because the working positions are all over the place. Therefore I changed them to look at the OSEMINF_*_OUTPUT channels.

In userapps I edited 

^/trunk/cds/h1/medm/H1CDS_SUS_OSEM_OVERVIEW.adl

and 

^/trunk/cds/h1/medm/H1CDS_SUS_OSEM_LARGE_OVERVIEW.adl

with gedit to change all instances of _INMON to _OUTPUT and all instances of hoprDefault=32000 to

loprDefault=-350

hoprDefault=350

where 350 = 15000*0.0233333. With these limits the working position of each indicator should be vertical if the GAIN and OFFSET fields are set to normalize raw signals in the range 0 to ≈22-31K to exactly ±15000 (per the standard SUS procedure), and FM5 is engaged to convert to microns.

After testing the changes I committed the files.
