The new design has the events list on the left and the calendar on the
right, so swap them around and remove the vertical separator between
them in favor of some additional whitespace as in the mockups.

The sass sources now live in a project in GNOME, so they can
be used in multiple projects like gnome-shell-extensions.
Because of that, add gnome-shell-sass as a submodule of gnome-shell
and remove the sass sources from the theme directory.
This used to be the style-class for status icons (i.e. icon-only
top bar items). It got unused a while ago when the class used
by status icons stopped using it - except for the keyboard indicator,
which set the class manually to appear as status icon despite not
being a real icon.
Now that the button highlight is provided by the .panel-button class
on a parent, the obsolete class results in a double border on the
keyboard indicator when active - just drop it from there as well
to fix.
- the goal is to have the items activate even on the edge
sadly this Fitzsiness is only working on the app vault icon
at the bottom, not the regular icons so far.
So we can style it differently than :hover.
We already have a active state for the menu items which includes
more than hover. For example, when the keyboard focus moves to a item
or we select programatically a item.
For this reason we need a style class named active for the meaning we
give to it in menu items, and a pseudo class active with the meaning
CSS has.

Since widnows decorations with round corners has a special shape,
which when scaled we can't match with a simple border-radius.
So to prevent to show a gap between the caption border and the
caption itself, apply a shadow.
