Strigidaemon

Here is another idea:

During initial indexing (this is the heavy cpu-loading one) show a progress 
dialog with a short explanation of what is happening (in the upper left or 
whatever). Let it have a "details" button which provides detailed information 
and direct access to basic configuration. This should include "cancel and do 
not start again" and "select the folders to index".

Once the initial indexing is done, only moved and newly created files should 
be indexed. That should be fairly little work for the cpu. An exception are 
files that are changed or added while strigi was not running. But that is 
another problem which IMHO should be addressed in a smarter way than just 
re-indexing everything. A possibility would be to save the last time strigi 
ran and only check files that have a later modification date. Then at least 
we would neither have to check the index nor the file contents for each file 
again.

Anyway, what do you think of the progress info for the initial run?

Cheers,
Sebastian
