It would be nice to have baloo support a "robots.txt" like functionality. That is, by a file in a folder (e.g. mypath/robots.txt) one can specify the index behavior for that path. E.g:
- do not index at all
- do not index certain mimetype
- type of indexing (basic or full)
- etc...

I don't care for the exact file name. It probably shouldn't be robots.txt because that could conflict with actual web content.

Ideally something with a leading dot, so it is hidden by default ".indexrc", ".crawlerrc", etc...
