- Moved thumnbail loading out of repo into ImageResizer. - Updated gallery and editor image handling to show errors where possible to indicate memory issues for resizing/thumbs. - Updated gallery to load image data in a per-image basis via edit form for more resiliant thumb/data fetching. Data was previously provided via gallery listing, which could be affected by failing generation of other images. - Updated image manager double click handling to be more pleasant and not flash away the edit form. - Updated editor handlers to use main URL when thumbs fail to load.
