[Nepomuk] Activities protocol

Hi Sebastian,

First of all, I hope you are on plasma-devel since a lot of people
didn't take me seriously concerning the cross-posting...

Yes, the apps report the name, window id and the uri of the resource
opened (be it a document, folder or some internal uri)

This is in the ActivityManager kded module.

I wasn't going for anything this pedantic (was trying to limit the
data and not remember every event) but it is fine with me to go that
extra mile.

The problem I see here is /suggesting/. The user usually opens a lot
of documents, and I wouldn't really like to have to ask him/her "do
you want to add this to the activity" for every one. That is, if you
have an idea about the UI that would make this job non-irritating, I'm
more than happy to hear it.
