add/remove.

This isn't a nice fix but the least evil version of a hack i could come
up. The source of the flickering is: We have a deeply nested structure
of widgets on the project pane. If we call hide() on such a deeply
nested widget, it will activate() it's parent layout synchronously.
That will then post an event (via updateGeometries() ) to its parent
layout that it needs relayouting. Which then will post to its parent
layout the same. And for each LayoutRequested, there's a painting in
between. The fix instead calls activate() up the chain until we are at
the viewport. This immediately relayouts everything. This adds a non
obvoius potentially for breakeage if the widgets are embedded in a
different widget hierarchy. But well, that's life.

Make sure that we give the QMainWindow always a valid layout before
restoring settings, so if something goes wrong with that, we don't end
up with a broken layout.

... to accommodate for the setup at Nokia.

QListWidget forward declaration was not namespaced.

...and give it some color and formatting.

This covers 'Y' in novisual, char and line mode and 'y' in char mode.
Visual block mode is still missing. It also fixes an off-by-one error
when displaying selection in visual char mode.

This may happen if a process exits after we got the /proc listing. If
we fail to open the file, readAll() returns empty, which means split()
returns an empty list, which means you can't do at(1).
