Added request_disk = 10MB to condor.py submit code.

Found that both "analyze" and "search" logs are < 0.1 MB, "online" logs to the lockloss directory so is request_disk needs to be barely anything for that. Spoke to Dan and confirmed a blanket request_disk of 10Mb for all methods (online, analyze, search) is fine. This is much larger than we expect but ensures our jobs won't be rejected. Fix removed the "must specify request_disk" message when tested on pcdev1.

Closes #181
