Switched coveralls image
Patched CKEditor with an 'upstream fix' for issue 11568, this re-enables selection of object styles when no element styles are present.
Also used a more permissive extraAllowedContent option, so any class (*), any style {*} and any attribute [*] are allowed on a and img elements.
