new formula: qwtpolar 1.1.0-rc1 - testing simpler formula with brewbot

new formula: qwtpolar 1.1.0-rc1
qgis will not build against qwt 6.1 w/o a newer qwtpolar library - which is only in rc status
qgis includes the qwtpolar source, however we won't see a new release until after 1.1.0 is final plus however long they take

#26153 beat me to it, however want to test this on brewbot since it's much smaller
will edit description after results
