Bug 9924 - Simplify and rename patron card creator error message include

The patron card creator error message include uses a non-standard method
for displaying error messages, and is poorly-named.

This patch converts the method of displaying error messages for various
patron card creator options to the standard one ('<div class="dialog
alert">') and renames the include file to make it clear that it relates
only to patron card creator operations.

To test, perform various operations:

- Go to 'manage images' and try to upload a file which exceeds the
  500KBfile size limit
- Go to the edit batch page and manually append an error code to the
  URL:  /cgi-bin/koha/patroncards/edit-batch.pl?op=new&error=403
- Go to one of the manage pages and manually append an error code to the
  URL:
  /cgi-bin/koha/patroncards/manage.pl?card_element=profile&error=201

Correct display of an error message indicates that the include file is
being found.
