Blasphemy! Custom modules had dupclicates. Removed.

A couple of custom modules including aap_tweaks had duplicate
modules present in the core drupal modules directory. This apparently
seemed to be so since ever. The dupclicates are now removed and only a
single copy is retained.

In the retained copy of aap_tweaks module, custom page callbacks to
include iframe content is removed too. Iframe embedding is now done via
basic page content and HTMLPurify module.
