Moving Baloo and Baloo-widgets into KDE SC

[Vishesh Handa]

Hey guys

I would like to move Baloo and Baloo-widgets into KDE SC soon. It would be 
nice if someone could review the code. Both the projects are in kdereview.

Baloo is a metadata and search framework which is a successor to the Nepomuk 
project. It primarily provides -

* An API for searching
* A way of storing relations between entities
* File indexing
* Email and Contact Indexing
* timeline kioslave

Baloo-widgets is a direct fork of nepomuk-widgets (history preserved). It 
offers the same widgets and API as nepomuk-widgets.
