Dataengine to get bookmarks

[Jan Gerrit Marker]

Hello,
I committed a dataengine to playground. This dataengine should get the 
bookmarks of various browsers like Firefox, Konqueror or Opera. At the moment 
it only supports Firefox.

As some of you may know I added Firefox support to the bookmark runner for KDE 
SC 4.4. I noticed that it is easy to get the bookmarks of Konqueror but hard 
to get Firefox's. So I thought it would be nice to get this data easily.
The dataengine uses the browsers as source. For every bookmark there are two 
entries: num-name and num-url where num is replaced with an integer value. Two 
equal integers mean that name and url are the ones of the same bookmark.

This makes it easy to access the bookmarks of different browsers without 
writing the code for getting them in every application. For example the 
bookmark runner could use this to get the bookmarks very quick instead of 
searching for them.
I hope you like this idea and I'd be glade if you would comment it. I know 
that this can't be added to KDE SC 4.4 so I hope I don't annoy you with this.

Greetings, Jan Gerrit Marker
