BatchUploader: several improvements
- Displays bibupload:batchupload in BibShed queue
- Adds the size of the input based on the length of the email address so that it does not get cut-off
- Does the conversion of textmarc to marcXML in the confirm step, to avoid the upload simulation from failing
- Removes option --insert when textmarc selected on the web interface as it is not supported by textmarc2marcxml
