Comment(by timlinux):

 Hi

 I upgraded both the lib parts and the plugin parts. A couple of new
 comments:

 - it would be nice to persist the last used dir for reference and raw
 images separately since these will often be in separate directories.

 - It would be nice to have an option to simply georeference the image (as
 opposed to orthorectify it) for those that dont have a dem handy.

 - I still get a crash when trying to gather GCP's between two images. The
 data is not publically shareable, so I will mail you a copy offlist.

 - It would still be nice to have a 'zoom to image' tool on the toolbars.

 - Thanks for updating to use the built in CRS selector from QGIS - much
 better usability.
