- Updated comment why we build without remote devices (boo#1091824)

- Update to 2.3.1:
* Update some translations.
* Set Smart rules 'files added in the last days' limit to 10*365.
* Only sort playlists in folders view, and place these after
tracks.
* Reduce width of statusbar spacer.
* Move scrobling 'love' button into toolbar. Use unfilled heart
before loved, and filled when loved.
* Better control of playqueue status bar buttons when
contracting/expanding.
* For windows, when adding local files (served via internal HTTP
server) add the real file path as a query item.
* Use smaller text for help text in Tweaks section of
preferences dialog.
* Fix playback of local non-MPD files under Windows.
* Stretching albums covers not working under Windows, so just
remove option.
* Don't enable AA_EnableHighDpiScaling for windows builds,
seems to interfere with fractional scaling.
* When playing, only poll MPD every 5 seconds.
* When updating play seekbar from MPDStatus, only upate if more
than 1 second from calculated position.
* Slightly reduce height of toolbar.
* Add a slight border to context view.
* Update suru icon - was a little too small.
* Don't attempt to align main menu for Windows < 10, as Qt seems
to add some menu animation that just looks weird when menu is
moved.
