Bug 11753 - Replace jQuery qTip plugin with Bootstrap tooltip on patron search form

The qTip plugin is out of date and incompatible with recent versions of
jQuery. This patch replaces use of qTip on the patron search form with a
Bootstrap tooltip implementation.

To test, apply the patch and view /cgi-bin/koha/members/members-home.pl

- Expand the patron search form by clicking the [+]
- Change 'search fields' from 'Standard' to 'Date of birth'
- A tooltip should appear giving details about the date format required
- Change the 'search fields' to something else. The tooltip should not
  appear.

Revision: Removed inclusion of qTip plugin from global header include.
The other instance of qTip usage occurs on a page which loads the plugin
separately.
