Issues with Gallery Manager

Going over the Gallery manager with Mathijs following issues are seen. If needed separate issues can be created for each:

• Setting the width and height of image variants does not seem to have an effect. Upon reload Essentials shows the original values, CMS also seems not to be updated

• Adding a new image variant, the new image variant is not stored in the galleryProcessorService. Upon rebuild and changing it again the following error is thrown:
  ERROR pool-4-thread-1 [Exporter.exportContentResource:133] Exporting configuration/frontend/cms.xml failed.
  javax.jcr.PathNotFoundException: /hippo:configuration/hippo:frontend/cms/cms-services/galleryProcessorService/essentialstest:bigimage

• When adding multiple image sets, for each a document type with the name 'Image' is created. This is confusing. Each document type must have a unique name (eg name of the image set)

• When adding multiple image sets, only one can now be used uploading images in the CMS. To make this useful a folder should be created per image set with the folder configured for the gallertype of that image set. Without that it is better to only support 1 image set.
