The code previously was using CSS to define row/column spacing and
padding which was combined with a subicon size computed in code relative
to the requested icon size.
In smaller icon sizes it was possible for the CSS spacing+padding + the
size of the two subicons to exceed the requested icon size. This then
would lead to the label being pushed down for app folders compared to
other icons.
Another more severe issue caused by this would happen if the first item
in an icon grid was an app folder. Then the calculation for the maximum
allowed icon size could be off, leading to all icons in the grid
becoming smaller than actually necessary.
This commit changes this to use homogeneous row and column layouts to
evenly distribute the remaining spacing instead of using a fixed CSS
value.

The Frequent apps grid has a few problems:
* On a fresh install there would be no history of app usage so the
applications shown in the grid have no relevance it takes time
to be useful instead of being useful from the start;
* The grid has far too many items in it to be relevant; 24 apps is
well beyond the average use case as most people don't frequently
use that many, so it gets populated with several apps that are
single use (hello xterm);
* The position of items in the grid are always changing based on an
unknown frequency metric (and not by user-intended input) which
makes it a poor way to quickly launch apps as one would have to
constantly learn the positions of the items in the grid;
* Having two app grids is a bit superfluous and needlessly complicates
the app launching navigation: you have to spend time checking the
frequent grid and if it's not there you have to switch over to another
grid and find the app you need in there it's not straightforward.
Remove the Frequent tab and simplify the related code.

- Remove margin-bottom for StIcon, which is not only ineffective, but
also created a bug in app folders.
- Remove ">" which is invalid for overview icons that are not app
folders.
- Apply spacing to the correct target "StBoxLayout", not the parent
.overview-icon.overview-icon-with-label.

- the plan was to drop the frequent/all view switcher, thus sam didn't
pay too much attention to the button styling for those. Sadly the view
switcher remains, so we should keep the old subtle styling intact.

Make the AppFolderPopup behave much more like a dialog than a
popup itself. To do that, remove the BoxPointer and replace it
by a StBoxLayout. The dialog is is also bind-constrained to the
view selector.
