[TJ, Jenne]

After hand-testing the new SR2 alignment states in ALIGN_IFO (alog 50823) during an initial alignment this morning (took ~3 min of testing), we've added logic into the SRC_ALIGNING state of INIT_ALIGN such that if it sits trying to lock the SRY cavity for more than 1 minute, give up and try aligning SR2 only (after having misaligned SRM). Then, once that's done, go back to locking and aligning the SRY cavity.

This new logic of automatically switching between the various levels of SRC alignment haven't been tested yet, and hopefully we don't need them before tomorrow's maintenance recovery.
