BUG: Some format_chooser issues fixed.

* If the transform plugin wasn't activated, setup did not work
  (missing strings).
* The input formats were ignored - they still are for collection_download.php,
  though - I need to think of a good solution to use there.
* Now, the view.php download area will look just as usual if the source file
  doesn't have an supported input format.
* Removed unused width/height from JS size info array.
