Add script offset / delay to Handy support. (#1573)

* Add script offset / delay to Handy support.

Further work on  #1376.

Offsets are added to the current video position, so a positive value leads to earlier motion.  (The most common setting.)

This is needed because most script times have a consistent delay when compared to the video. (Delay from the API calls to the server should be handled by the server offset calculation.)

* Rename scriptOffset to funscriptOffset
* Correct localisation keys
