----------------------------------------------------------------------------
Minor improvements:
 - Fix button enable/disable when image list is empty (ImagesList)
 - Fix button enable/disable on new album dialog
 - Check FileSizeLimit before upload
 - Keywords, GPS coordinates support
 - Implement validators for email and password

Short term:
 - video file upload - do not perform resize

Long term:
 - Synchronize with local album (upload/download)
 - Virtual albums (needs support in KIPI and Host application)
 - Support for adding categories/subcategories (is this needed?)
 - SmugVault support?
