Since we have now destkop and mobile versions, 'qt-ui' was a very poor name choice for a folder that contains only destkop-enabled widgets. Also, move the graphicsview-common.h/cpp to subsurface-core because it doesn't depend on qgraphicsview, it merely implements all the colors that we use throughout Subsurface, and we will use colors on both desktop and mobile versions Same thing applies for metrics.h/cpp Signed-off-by: Tomaz Canabrava <tomaz.canabrava@intel.com> Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
