This commit implements the starred items functionality
both in Tracker class and throughout the UI. Also, it
adapts the StarredView to work.

If we read an item in the News view and directly jump
into Feeds view, the item is not marked as read.

Fix that by updating items when something changes on
Tracker side.

Tracker should be fast enought to not lag, and we're not
really working with thusands of feeds right now.

It works now. Thanks to Carlos Garnacho for the
unvaluable help.

Instead of using a stack sidebar and adding hacks
all around, simply use a listbox and manually manage
the feeds.

With this patch, feeds are also added alphabetically
sorted.

It is a very poor design choice to make the parent class
handle the subclass implementation details. As such, move
the subclass specific code to the subclasses

This doesn't quite work yet, probably because of an
error in Sparql query. But we finally have something
to work on.

Time already proved us that crafting UI in
source code is a very bad idea. This commit
adds a new window.ui resource, and loads the
window widgets from this resource.

As pointed out by Garnacho, we have to remove
the whole resource.

The GenericFeedsView abstract class currently adapts
the layout according to the show_feedlist argument. It
turns out that this is a poor design choice, and a better
and more sustainable path is to delegate the layout
setup to the subclass.

Fix this by moving the layout code to a separate function
and override this function in FeedsView.

Set it modal to the parent window. Also, avoid accessing
a private field from the parent application.

Currently, the resources are spread all around
data/ folder. This, per se, is not a problem, but
we can save some code by delegating to Gtk+ some
things like loading the app menu.

Fix that by better organizing the data/ folder, and
updating the application to reflect that.
