[Tracker] Evolution support (IMAP)

[Michal Pryc <Michal Pryc Sun COM>]

Hello tracker developers!

I was testing evolution support for tracker and I run into one problem. 
I have thousands of e-mails in different subdirectories on the IMAP, so 
I did checked one subdirectory for offline browsing, which is needed by 
tracker and here problem started.

The tracker are going through all of the e-mails in every subdirectory 
even if it is not selected for offline browsing, which takes ages. In my 
opinion this is not ideal concept.

It would be *much* better if tracker could take information which 
directory is actually *selected* for offline browsing and that go 
through only those ones.
