image display: added normalization option for 16 bit mono images
[bugfix] Make PanelDockWidget disable associated display only when pressing close button, not on any visibility change. Fixes #520
prevent window from growing when config is saved.

Use the content geometry (width() and height()) instead of the frame geometry
(frameGeometry().width()/height()) to save the width of the top level window
since this is what is set by the resize function.  Use the frame position (x()
and y()) for saving position which is what move() sets.
renamed PanelDockWidget::closed() to closeButtonClicked(), improved header doc

Merging pull request to save window size correctly.

The result is still not perfect on my window manager (Unity) but it is a big improvement anyway, so merging.
PanelDockWidget::closed() triggered on any close event, be it the close button or through the toggle action (from the papnels menu). Also, re-enable associated display when visibility set to true from somewhere
Display: made associatedPanelVisibilityChange(),disable() private

Replaced old surface-normal hack with better fix.

Surface normal vectors are now normalized at load time instead of tweaking the scaling to force Ogre to normalize them.
