Fixes #738: Implement file upload as a pure servlet

It is not the file upload itself that is the real problem, it is the fact that the upload is sent to a hidden frame and that it is difficult to handle errors (eg. show them to the user). The new solution is to simply let the error be generated in the hidden frame and then use a javascript callback in the parent window to re-size the frames so that the upload-frame becomes visible instead.

I have also got rid of the non-ajax version of progress reporter since this could also cause problems. The progress reporting is no longer responsible for any error handling (since it is possible for an error to happen before the progress reporting infrastructure has been setup).

    23   This page is used to display the progress of a file upload. The FileUploadProgress
    24   is put into the session setting by the upload.jsp page when the upload is started.
    25   If an exception is thrown during the upload we can get it by checking the
    26   FileUploadProgress.getException() method.
    27  
    28   If we want to abort the upload we use the FileUpload.setAbort() method, which is
    29   detected by the upload process and causes an UploadAbortedException to be thrown.
    30   This exception is also detected by the FileUploadProgress.getException() method
    31   before we display the message about the aborted upload.
