Move all scalebar rendering code out of composer and ensure that all scalebar rendering is done independant of QgsComposerScaleBar This allows scalebar rendering code to be reused by plugins and by non-composer code. Also rename QgsScaleBarStyle -> QgsScaleBarRenderer, (and all subclasses too). This name better reflects what these classes do.
