Release 1

Initial release.

Tested with:

• Firefox (Windows) (Greasemonkey 4)
• Pale Moon (Windows) (Greasemonkey 3.3 RC4)
• Iron (Windows) (Tampermonkey)

Notes:
Support for the "TV Recording" video type is untested. I was unable to get my DiskStation to work with my DTV adapter.
Support for Linux and other operating systems, and indeed anything not explicitly tested above is not guaranteed.
Feedback about operating system and browser compatibility is welcome.
