Bug 37848: Fix "Run with template" dropdown menu style

Bug 37848: Fix "Run with template" dropdown menu style

This patch adds the missing "dropdown-item" class to the "Run with
template" dropdown menu markup in order to correct the menu's style.

The patch also adds a template ID to the menu items' id attributes so
that we don't have duplicate IDs.

To test, apply the patch and go to Tools -> Notices.

(testing steps copied from Bug 36157)

1. Create a notice with the module of "Reports" -- add something to the
   "Print" section. Example from the other bug:

    [% FOREACH b IN data %]
      <div class="panel panel-default">
         <div class="panel-heading">[% b.surname %], [% b.firstname %]</div>
         <div class="panel-body">Expiration: [% b.dateexpiry %]</div>
         <div class="panel-footer">ID: [% b.borrowernumber %]</div>
      </div>
    [% END %]

2. Create and run a saved report. Example from bug 36157:

    SELECT * FROM borrowers

3. Click on the "Run with template" dropdown and confirm that it is
   styled correctly.
4. Click to run the report with the template and confirm that it works
   correctly.
