Server network layer: modified the way in which requests handle SSL auth. Now they are enqueued to the threadpool before doing any network reading, to free the network callback as soon as possible. This should fix a weird deadlock detected on a Linux server after hours of intense work (while others with even more load go fine).
Windows: The cm diff command wasn't using the appropriate file extension when downloading temporary files. This caused the image diff to fail if a particular changeset was used in the revision spec. Fixed.
CLI: The cm diff command failed (throwing a null reference exception) when a revision was specified by ID. Fixed.
