Add symbolic icons for actions
Merge pull request #3079 from RavetcoFX/a31

Add symbolic icons for actions
Fix new symbolic icons, change their category so they stay consistent with
the other icons
Add show-desktop toggle to hotcorners
Fix assertion when starting cinnamon-settings-users
cinnamon-settings user: fix accidentally adding a widget twice
Make new menu icons for desklets and backgrounds non-symbolic, and
place them as a sized icon rather than scalable.  This will ensure
the correct icon is picked and scaled regardless of the hidpi mode.
system tray: rework a bit, to address #2566 a bit.

- Fixed the sizing issues at the gtk plug level
- simplified the applet
- improved a race condition where the tray icon may have been destroyed
  before the applet had a chance to add it to the panel
     TODO:  this is *still* a race condition - there should be a callback
            that triggers the continuation of the low level na_tray_manager
            handle_dock_Request.
st-texture-cache.c: stop returning null suring a load_gicon call - always
return a ClutterActor, even an empty one.
Remove extra GC calls - causes random freezing
cinnamon-desktop-editor: handle the exec line better, don't allow an
invalid (and therefore possibly inaccessible) desktop file to be created.  Fixed
handling of spaces in the exec line as well.

Also fixed a random issue where removing launchers in the panel launcher applet
would end up removing the wrong launcher.
schema: clarify panel height setting descriptions.
Tweak Section class slightly
Adjust the default size of the mouse settings window to stop it from opening with a scrollbar
