Quilt patch management with debhelper 7

Since quilt 0.46-7 (see #527255) you can automatically apply/unapply a quilt patch serie with debhelper’s dh command. It’s very practical in tiny rules files:

%:
	dh --with quilt $@

There’s also dh_quilt_patch and dh_quilt_unpatch for those who don’t use tiny rules files.

Enjoy !
