Javascript behaviour should only be ran once (results in nested tabs)

Problem/Motivation

The Drupal.behaviors.moduleFilterModulesTabs behaviour should only be ran once, otherwise anytime there's a new ajax request on the page e.g. if the Automated Logout module is enabled and doing its check, the behaviour is ran indefinitely.

Resulting in nested tabs:

Steps to reproduce

Enable the Automated Logout module and wait for an ajax request to be called.

Proposed resolution

Apply the appropriate behaviours once on the parent page.

The context variable should also be used during jQuery calls to ensure that the code works with AJAX requests.

Remaining tasks

Update javascript behaviours to support AJAX requests.
