Bug 17083: Remove more event attributes from tools templates

This patch removes event attributes from several tool-related templates.
Events are defined instead in the JavaScript.

To test, apply the patch and:

- Go to Tools -> Label creator -> Manage -> Layouts and edit any layout.
  - In the "Font" setting, choose any font which includes the word
    "italic" or "oblique" in the name. Doing so should disable the
    "Oblique title" checkbox.
- Go to Tools -> Batch patron deletion/anonymization.
  - Submit the form without making any changes. You should be prompted
    to select an action.
- Go to Tools -> Inventory.
  - Select a batch of barcodes to upload.
  - Submit the form without selecting any filters. This should trigger a
    warning.
  - Also changed: Added Font Awesome icons to the "Select all" and
    "Clear all" links on the inventory results view.
- Go to Tools -> Notices and Slips.
  - Click "New notice"
  - Change the selection under "Koha module." The page should reload
    with the correct available message body fields. For instance,
    selecting "Holds" should make available reserves.* columns.
- Go to Tools -> Upload.
  - In the search form, enter a search term and click the 'Search'
    button. The form should submit.
