Bug 30494: Replace the use of jQueryUI Accordion on the table settings page

This page updates the table settings page so that it uses Bootstrap's
"Collapse" feature instead of jQueryUI's Accordion.

To test, apply the patch and rebuild the staff interface CSS
(https://wiki.koha-community.org/wiki/Working_with_SCSS_in_the_OPAC_and_staff_client).

- Go to Administration -> Table settings.
- You should see a list of table settings which looks much the same as
  it did before, with arrow icons prefixing each section header. All
  panels should be collapsed.
- Test expanding and collapsing panels to confirm it's working
  correctly.
- When you expand a section the heading arrow should change from
  right-pointing to down.
- Make a change to one of the table configurations. After clicking
  "Save" the page should reload with the same panel expanded.
