using a modifier key instad of a configurable shortcut
moved wallaper handling to seperate object
Wallpaper is loaded directly instead of data-url.

Needed to revise loading policy for that as well.
better checks for load delegation. Not quite happy yet
Using policy delegate instead of load delegate.

Opening links seems to work fine now (Issue #12)
Using 127.0.0.1 instead of localhost (Issue #36)
Improvements to wallpaper server (Issue #42).

- Detecting wallpaper changes by listening to file changes to settings db.
- Rapid changes are batched together.
- Wallaper urls are uniq per change.
- Renamed wallaperDataUrl to wallpaperUrl
avoiding memory leaks by not storing wallpaper slices
less aggressive come to front behaviour
More wallpaper server improvements.

- making sure server is started
- removed debug statements
