unity-scope-click will get a list of installed applications with
"click list --manifest", and build uris for each scope result like:
"application:///home/phablet/.local/share/applications/pkgid_appid_version.desktop"

Some duplication may happen because unity-lens-applications will also
be parsing the .desktop files in that same folder, so we are planning
to de-duplicate using just one of the following:

 * deduplicate on the dash, based on the application:// uri,
priorizing results from u-s-click
 * or, filter .desktop files on unity-lens-applications that have the
"X-Ubuntu-Application-ID" field (meaning they are apps installed by
click)

we've not decided which method we'll use yet, so any comments are appreciated.

cheers,
