Fixes: Changes in skipping files and suggested path in qrc editor

RevBy:    Thorbjorn Lindeijer
Details:  Renamed button "Don't Add" to "Skip". The button is only
          shown, if more than 1 file shall be added. In addition to
	  that the qrc editor checks, whether there is a "Resources"
	  directory in the qrc-file's folder and sets this directory
	  as the suggested save dir, if present (Needed in the Visual
	  Studio Add-in)
