Don't reset .stversions attribute to hidden on each restart (Windows)

Hi

Some users … (well … me :slight_smile: as I send too much time with friends to teach them about the trash can according to syncthing) would like to keep syncing files and .stfolder & .stignore hidden, but would like to see .stversions. Unfortunately, when we unset the hidden attribute, then on each restart ST resets the attribute. Nuxes have Ctrl+H which is enough.

Extra bonus would allow us to use a custom (read localized) name for this directory as we already can do for markerName .stfolder.

Whatever, go on guys, this thing is a wonderful experience :sunny:
