fix bug 800914: Excise mindtouch, switch vagrant to ubuntu

* Switch to Ubuntu 12.04 LTS from CentOS for base OS

* Remove MindTouch installation manifests

* Perform `npm install` on kumascript, which ensures node-fibers build.

* Stop using a virtualenv for python libs, rely more on Ubuntu packages
  for quicker setup.

* General cleanup in Puppet manifests. Consolidate some simpler small
  puppet manifests (eg. Apache, MySQL, memcache, etc)

* New self-signed SSL cert, since we're not using CentOS' out-of-box

* Tweak to wiki South migration #10 to ignore attempt to delete an index
  that's already gone.

Fix bug 823733: Rework RevisionForm save logic for section editing.

This adds a separate code path (largely because I suspect we're going
to find more things that need to be different in section edits) for
saving a section edit, and ensures that the existing show_toc and
review_tags are preserved (since they're not submitted in a section
edit).
