Bug 29998: Replace the use of jQueryUI tabs on item types administration page

This patch updates the item type edit interface so that it uses
Bootstrap tabs instead of jQueryUI tabs for displaying icon sets.

Unrelated: The patch removes an invalid "type" attribute from a <select>
element.

- Go to Administration -> Item types in the staff interface.
- Edit an item type.
- On the edit page you should see tabs under "Choose an icon."
- Confirm that the tabs look correct and work correctly.
- If you did not previously have any icon selected, the "None" tab
  should be active.
- If you had an icon selected, that icon set's tab should be active.
- Confirm that if you specify a remote image (e.g.
  https://via.placeholder.com/50/FF0000/FFFFFF.png ) the tab is
  correctly shown after you save and re-edit.
- Confirm that changing icons works correctly and that the selected
  icon's tab is always active when you return to the edit view.
