Capx 24 [incomplete]

This is at a place to review...

As per title, this is incomplete. Jira has some more details.
Major points of contention in this PR:
* Unnecessary API changes.
* jqTree Apache license requires the CAPx module to be GPLv3.
This doesn't need to be in the menu. Please change to MENU_SUGGESTED_ITEM so that site admins can decide.
