new strings in unity-scope-mediascanner2 and unity-scopes-shell, translations needed

[Pawel Stolowski]

Hi,

New strings were recently added in the trunk branches of 
unity-scope-mediascanner2 (music and videos) and unity-scopes-shell:

- "Get started!", "Drag and drop items..." and "Nothing here yet..." in 
unity-scope-mediascanner2; these strings are visible if no local 
music/videos are present on the phone for this scopes (a special
"get started" card is displayed).
- "Display results from" in unity-scopes-shell project - this string is 
visible in the settings of music / video aggregator scopes.

The unity-scopes-shell didn't have translations before (this is the 
first string there), so let me know if there are any problems with them.

Thanks,
Pawel
