Track watch activity for scenes. (#3055)

* track watchtime and view time * add view count sorting, added continue position filter * display metrics in file info * add toggle for tracking activity * save activity every 10 seconds * reset resume when video is nearly complete * start from beginning when playing scene in queue Co-authored-by: WithoutPants <53250216+WithoutPants@users.noreply.github.com>

 ### ✨ New Features
+* Added ability to track play count and duration for scenes. ([#3055](https://github.com/stashapp/stash/pull/3055))
+* Scenes now optionally show the last point watched, and can be resumed from that point. ([#3055](https://github.com/stashapp/stash/pull/3055))
 * Added support for filtering stash ids by endpoint. ([#3005](https://github.com/stashapp/stash/pull/3005))
 * Added custom javascript option. ([#3132](https://github.com/stashapp/stash/pull/3132))
 * Added ability to select rating system in the Interface settings, allowing 5 stars with full-, half- or quarter-stars, or numeric score out of 10 with one decimal point. ([#2830](https://github.com/stashapp/stash/pull/2830))

 The maximum loop duration option allows looping of shorter videos. Set this value to the maximum scene duration that scene videos should loop. Setting this to 0 disables this functionality.

+### Activity tracking
+
+The "Track Activity" option allows tracking of scene play count and duration, and sets the resume point when a scene video is not finished.
+
+The "Minimum Play Percent" gives the minimum proportion of a video that must be played before the play count of the scene is incremented.
+
+By default, when a scene has a resume point, the scene player will automatically seek to this point when the scene is played. Setting "Always start video from beginning" to true disables this behaviour.

 ## Custom CSS

 The stash UI can be customised using custom CSS. See [here](https://github.com/stashapp/stash/wiki/Custom-CSS-snippets) for a community-curated set of CSS snippets to customise your UI.
