Integrate Fwk updates from ResInsight/Perforce

Integrated Fwk updates in Resinsight branch up to changelist 173.
Summary of changes:
* Rewrite of cvf::OverlayItem to allow fixed user controlled positioning
of the items.
* Removed pure virtual functions OverlayItem::maximumSize() and
OverlayItem::minimumSize().
* Use caf::AboutDialog instead of modified cvfqt::BasicAboutDialog.
* Removed lapack from link line due to fail on Ubuntu 12.04 when lapack
isn't installed.
* Fix in OpenGLContext::saveOpenGLState() to avoid application
corruption when running on RedHat with VMWare.
* Removed unused font manager.
* Console assert handler only calls __debugbreak() if debugger is
present. Otherwise, calls abort(). Done after trouble running gtest
death tests.
* Made component access functions in Color3f, Color3ub, Color4f,
Color4ub inline.
* Added conversion functions between TextureImage and QImage to
cvfqt::Utils class.
* Optimized TextureImage::setPixel() - relies on new inlined
component-wise access functions for Color4ub.
* Added TextureImage::clear() and non-const version of
TextureImage::ptr().
