v1.1.2-nrkno

• fix: don't run watchdog on startup (to allow for the initial work to be done)
• feat(scanner): add options for black and freeze detect

v1.1-nrkno

Added "watchdog", a self-check that the file watching and database works.

To activate the watchdog functionality:
Place a file called "watchdog.mov" in the media folder.
The watchdog function runs every 5 minutes and:

• Makes a copy of watchdog.mov
• checks that pouchdb updates with the changes
• Removes the copy of watchdog.mov
• checks that pouchdb is updated

(This functionality is intended to be used when the media-scanner is hosted by a host that restarts it if it closes, as the watchdog simply process.exit():s if the test fail)
