Description of problem:
When source documents are uploading, a user can attempt to close the upload
dialog by clicking outside it, clicking 'cancel' or clicking the X at the top
right. Attempts to close the upload dialog cause a warning to be displayed, for
the user to confirm canceling the upload.

Usability would be better if the user could close the dialog with no warning
and have files continue to upload. Summary upload progress could be shown in a
widget, and the user could re-open the upload dialog to see the detailed
progress information.

A warning would generally still be necessary when closing the page due to
technical limitations: the file selector elements that are necessary to upload
(due to browser permissions) would be reset, and could not return to their
previous state without user intervention.


Steps to Reproduce:

1. Navigate to document settings in a version for which you have file upload
permission.
2. Open the source document upload dialog.
3. Input one or more documents, of sufficient size to allow some clicks before
upload completes.
4. Click 'Upload Documents'.
5. Before upload completes, close the dialog by clicking any of:
  - the 'X' at the top right of the dialog
  - the background outside the modal
6. Re-open the source document upload dialog.

Actual results:
5. A modal warning is displayed asking for confirmation to cancel the upload.
6. The dialog opens and is in the default state with no files.

Expected results:
5. The dialog is closed, a widget shows that upload is occurring and updates
regularly to indicate the ongoing progress of the upload. The widget is grouped
with the  that opens the source document upload dialog.
6. The dialog opens and shows the continuing progress of file upload as though
it had not been closed.

The 'Cancel' button should still stop the upload, but should cause a widget to
be shown that indicates that the upload is stopped, and that offers a 'resume'
operation.
