Fling to close tasks in the GestureNav can be too small.

Browse Source 
The problem is that the velocity threshold to activate the fling
was set using pixels per second, so a better aproach would is to
use dp/s. So now there is a variable set in the dimes.xml file
called base_swift_detector_fling_release_velocity.

Test: Manually tested
