Make avahi mandatory, it is not possible to disable
it anymore [1].
Strip binaries by using install-strip instead of using
${STRIP_CMD}.

compact.

Bring back nautilus-actions:

	- Drop gconf support. It is optional in the sources, so
	  we can make it optional if needed
	- Force gtk3 instead of gtk2
	- Do not install .la files, this is a leave port so we
	  can do that safely
