Anvil - Templates / Themes Module - ckeditor update

[Reconix]

NOTES:

At the moment the settings for ckeditor are getting pulled from ckeditor config, making things easy to edit in one place, the final idea being in the back end one could easily change those settings via "My Site Preferences" page.
However, this could further be organised better by having a new system config page, allowing you to set what editor you'd like to use if any and then pull default settings allowing you to edit what you'd like.

For now, just pull the basics like in v1, ditch lib and helper.
