- inkscape.rc/inkview.rc are automatically configured with the
  correct program name, version number and copyright year
- use one common file for all four configurations
  (inkscape/inkview, x86/x64)
  which should make it much easier to maintain and keep in sync
- fix/update/add some fields in the resource file, see
  https://msdn.microsoft.com/library/windows/desktop/aa381058.aspx
- also unify inkscape-manifest.xml
  As a result all configurations will use dpiAware=True now
  (x86 and inkview did not have that setting yet)
  This does not matter in gtk3 but is known know to cause tiny icons
  on gtk2. It's still the preferred option as everything else
  (including canvas) is properly scaled; if bitmap interpolation
  is more desirable instead the setting can be overriden in the
  compatibility tab of the executables properties dialog
