preparation for 20bit DAC install on h1susetmx

Attached image shows the model changes I have made to h1iopsusex.mdl and h1susetmx.mdl to replace the 5th 18bit-DAC with a 20bit-DAC. I've changed the color of the part so it stands out as a different type of DAC.

In order to compile the code, I had to rewind some code prior to Jenne's latest TRIG_IFO changes. This was done using a SVN backwards merge. This table shows filename, Jenne's latest version number and the version I went back to

QUAD_MASTER.mdl r18073 r17922
FOUROSEM_DAMPED_STAGE_MASTER_WITH_DAMP_MODE.mdl r18073 r17922
FOUROSEM_STARGE_MASTER_OPLEV_TIDAL.mdl r18073 r17922

All files are in svn/common/models

I also edited sus/h1/models/h1susetmx.mdl to:

Remove the TRIG_IFO IPC part which connected to the new input port on the QUAD_MASTER

Changed DAC_3 from 18bit-DAC to 20bit-DAC

To re-install Jenne's code, we just need to "svn revert" the common models and edit h1susetmx.mdl to add the new RFM-IPC receiver and connect it to the QUAD_MASTER block.
