Uploaded Files Dialog: Improve overview + UX #16
Description
- Improve File Display (icon + tab), truncat long filenames, extend column
- Hide native "Durchsuchen" Button button with styled version, trigger upload on select, see angular-image-upload-made-easy
- Allow overwrite name for uploaded files (currently only for URL Pull), see also truncate-string-with-ellipsis
- Support "Set as primary image" link action per file, so managed file becomes the "Title" image
