Wallpaper refining (#81)

* Wallpaper refining

- Swww: allow all images formats supported by Swww but only show the one
we can render in the panel
- Fix: timer should be restarted when selecting a wallpaper
- Fix: avoid recomputing selected thumbnail by altering the border width
- Removed LazyLoader as it was not helping

* Wallpapers changes

- revert: maintaining a single list all wallpapers, support only basic
images format.
- settings: reordered wallpapers settings and made the Swww settings
conditionals to activating the useSWWW toggle

* Fix broken avatar display in Panel, Settings and LockScreen
