Bug 9310 - Patron image upload template corrections

This patch fixes some template structure problems and makes some
improvements:

- Correct grid structure so that page isn't narrower than it needs
  to be.
- Move image upload messages out of message/error dialog and into
  table so that lines are distinct and legible.
- Expand breadcrumbs specificity
- Capitalization corrections

To test: Upload patron images using both single images and zip files.
Test zip file upload with a file which contains valid and invalid
contents (non-existant patron numbers, invalid image files, etc). In all
cases image uploads should work correctly and errors should be legibly
displayed.
