[Qgis-developer] spatial joins and select by location should not consider polygons than only touch

[G. Allegri]

Hi Andreas,
I'm doing it :)
As you can see I've added the checkox options to have fine control on
spatial relations. I could add the threashold value as well.
I know we are in feature freeze, I'm doing it for the next 2.5/2.6. Should
I wait for 2.4 release before submitting pull requests with new features?
