Editor Fields were used to inject HTML, but the fields were
not pointing to Editor Field directly. They were pointing to
Base_viewWebFieldLibrary/my_text_content which is designed to
use a real editor (Gadget Field now) instead of inject HTML.

Some fields were changed to point to Editor Field in order to
inject HTML.

Base_viewTestPageFieldLibrary/my_embedded_text_content is also
changed to use a simple text area, like it should be originaly
designed for.
