Fixed problem trying to call QLineEdit.setPlaceholderText within Nuke.
Gaffer.BlockedConnection now supports reentrancy, with the connection only becoming unblocked when the outermost block has been exited.
Fixed bug which prevented selection using the up/down cursor keys from working in the PathChooserWidget.
ImageGadgets now have a linear to srgb conversion applied when they are drawn. This means they now match the Image widget behaviour.
PathChooserWidget and PathChooserDialogue now accept a new allowMultipleSelection argument to the constructor. Use the new PathChooserDialogue.waitForPaths() method to wait for paths selected in this way.
VectorDataWidget has a new protected _createRows() method which may be overridden by derived classes to customise the addition of new rows. The PathVectorDataWidget implements this by displaying a dialogue where the user may select multiple paths to be added. This improves the parameter ui for PathVectorParameters.
