fixed a few errors in Proposemode: overriding B_BAD_VALUE is fixed, aborting with B_ERROR for dualhead modes in singlehead only colorspaces is fixed (routine continues with B_BAD_VALUE and in singlehead mode then). Bumped version to 0.21. It's refreshing to look from the Screenprefs app perspective :). Fixes done for 'unofficial prefs panel' Dualhead Setup 0.04 optimum compatibility (will be released soon).
