Added preliminary support for a Manual Display Widget.

Added a preliminary support for a manual display widget,
it's a very basic HTML text-browser, so it can have
hyperlinks, images and everything that a 1995 browser
has.

The long term plan is to subsittute this manual by
a more modern 'help' using QGraphicsView, that will
interact on the application level.

See #121
