Save CachedFileData to disk

Since we already have the data, save it to speed up the start.

Surprisingly, the hardest part was to figure out how to use
QStandardPaths to find a location where to save the file. I went with
the semi-hardcoded path HomeLocation/.shemovcleaner, even though we're
on windows.
