Aligned the cavity using tdsdither @ 19:20.

Left the cavity locked w/o VCO offloading servo to ETMY so we can make a (somewhat) longer term comparison of the ETM angle with (yesterday) and without (tonight) the length drive.

Also QPD servo was disabled so we can see how good or bad the alignment is going to be without active pointing servo.

ETMY L1 damp filters are on (as usual only for L and P).
