in particular, fix line continuation processing.

also, reintroduce some error handling. it checks only one condition so
far (malformed assignment statement) and is entirely silent, but that's
all that was necessary for internal robustness.

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.

Mainly squash compiler noise about 'offsetof'.

... to accommodate for the setup at Nokia.

Also fixed a bug uncovered by the auto test.

Also added checks to guard against these kind of changes in the future.

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.
