HAM1 Vent work - added Beam dump (PM1) and Cable table bracket (RM1)

- Cable table bracket for the bosem cables have been added to RM1 suspension in HAM1 - see here.

- Beam dump for catching the transmitted light through PM1 optic has also been attached as shown in several pictures attached below. Camilla and I adjusted/fine-tuned (angle etc.) it as well.

Also, I thoroughly inspected PM1 (BOSEM flags and mirror holder) for any rubbing or touching, didn't find anything. I adjusted the BOSEM bracket for my own satisfaction, since one or two of the BOSEM flags were not exactly looking centered between the PD/LED, however the adjustment was minimal (the bracket could hardly move) and didn't create much of a difference. I will be posting the measurement results asap.
