Enabled fullscreenEnabled configuration setting, which allows you to disable the full screen button if desired.
Ticket #215 - Added docs
Ticket #212 - Make sure if content is in the textarea on page or JS load to use
that as the initial content for the editor. Still needs tests for this use case!
Ticket #212 - Finalize changes for bug where the editor should use the content
in the textarea as the content in EpicEditor's editor if content exists in the
textarea on page load. Commit adds tests on this as well as notes in the docs.
It also pulls out the textarea option into a private (on the prototype) method
to clean up the load method.
