added a protected constructor to GafferImageUI::ImageView that accepts a Gaffer::Plug, so you can create derived classes that don't necessarily accept a GafferImage::ImagePlug
Merge branch 'master' of https://github.com/ImageEngine/gaffer
added some fallback code in the maya part of GLWidget, so if it doesn't find a sharing widget it makes one itself, meaning things don't break quite as badly
updated changes, bumped patch version
