In fswatcher, update the cache if mtime changes; otherwise an mtime change without an md5 change will cause the file to be rechecked every time. This was triggered in a painful way by fswatcher's cache being populated with mtimes from the cache files. Flush the fscache after an initial fine-grained upgrade, which could cause certain changes to be missed temporarily. Don't compute hashes for the whole source tree redundantly in caching mode, which saves a bunch of time on initial load.
