location: Only show menu when geolocation is in use

Users can now toggle geolocation off/on from privacy panel of
gnome-control-center so we don't need to clutter the menu with a
settings that most users won't touch most of the time.

appDisplay: Animate AllView and FrequentView

Following design decision, we want to animate AllView and FrequentView
when opening and closing with a swarm spring form.

This involves a few changes needed to allow that, since from some time
now, we are animating page changes in viewSelector, using only a fade
transition. However now we want to let appDisplay and iconGrid apply its
own animation.

For that we special case the change to and from apps page on
viewSelector to let appDisplay to animate its own items, using and API
on appDisplay which at the same time uses an API on iconGrid.

However animating the icons in iconGrid involves a few challenges due to
the current need of scaling icons on iconGrid on a call which uses
BEFORE_REDRAW.  We need to call animate() after the icons are already
scaled, that means however, calling after a BEFORE_REDRAW, so that
means, we have to call animate() in a call using BEFORE_REDRAW which
call a function using BEFORE_REDRAW as well, so we wait two frames to
make sure icons are scaled correctly.

Thanks Florian Mullner for the debugging work

appDisplay: Animate indicators out

Given that we animate indicator in, it makes sense to animate them out
as well.

search: Allow providers to return the complete result object

 This makes the existing createResultObject() match its name better
 and avoids oddities like nested StButtons in app search results.
search: Remove DND code from GridSearchResult

Providers that need drag-and-drop behavior can implement this via the
createResultObject() hook (as the app search provider already does), no
need to duplicate that code in the generic result objects
(ListSearchResult already does not implement DND).
