[Jamie, Arnaud]

Some SUS guardian updates from yesterday :

- all sus guardians have been successfully restarted after Jamie's modifications to SUS.py.

- Sheila thought it would be useful to add a saving feature for the alignment of TMSX with the itmx baffles PD1 and PD4, so align_save_burt was modified to add the option of saving "aligned to pd1" and "aligned to pd4" snap file.

Usage :

./align_save_burt -t alignedtopd1 TMSX
saving alignedtopd1 tmsx
 /opt/rtcds/userapps/release/sus/h1/burtfiles/h1sustmsx_alignedtopd1_offsets.snap

- This has been added to the OPTICALIGN medm screen of TMSX and TMSY as well as the IFO_ALIGN (cf TMSX_OPTICALIGN.png and IFO_ALIGN.png)

- Two states were created for SUS_TMSX and SUS_TMSY ALIGNED_TO_PD1 and ALIGNED_TO_PD4. They simply load the files saved by the align_save_burt script

- Edges between the different alignment positions were added for SUS_TMSX and SUS_TMSY to avoid going through the DAMPED state (which turns off the alignment offsets) during transition between different aligned states (cf TMSX_graph.png)

What need to be done/discussed :

-Turning off the alignment offsets seems to be enough to misalign the suspensions, so I'm wondering if we need to keep the misaligned state (except for PRM)
