Remove CKE 4.2.0
Fix typo per @Da-Fecto issue #13
Some small updates including moving the purification to it's own function and setting the 'entities' option to false.
Update CKEditor to version 4.3.2, plus correct method we used to retrieve the HTML from inline mode, so that Anchor links and other potential things won't contain CKEditor classes in them.
Add support for custom contents.css file specific to inline mode (previously they weren't supported). Also update README with tips and tutorials.
