Since oplev damping might be used for Y arm commssioning as it is currently for X arm, I modified the QUAD_MASTER simulink model to have oplevs feedback on all the quads. 

• Created a common part called FOUROSEM_STAGE_OPLEV.adl living in /opt/rtcds/userapps/trunk/sus/common/models (copied from FOUROSEM_STAGE.adl) with a new path linking the oplev signal to UIM and PUM actuation (going through the DRIVEALIGN matrix) cf first screenshot.
• In QUAD_MASTER, the L1 and L2 parts were replaced with the newly created "FOUROSEM_STAGE_OPLEV"
• Hooked back h1susetmx and h1susitmx to QUAD_MASTER
• Modified the medm screens : Added a menu button at UIM and PUM levels. This screen might need to be revisited for clarity. Stuart is making a similar change at LLO with a better looking screen, so we will update when change is commited
• Took safe snapshots of the four quads with oplev switches off

Only FOUROSEM_STAGE_OPLEV.adl part was commited to the svn
