When editing a content without TinyMCE, no way to embed an image is available. I have not tested how it behaves for a content in FORMAT_MOODLE or FORMAT_MARKDOWN migrated from 1.9.

Reproduce:
1. turn HTML editor off in your profile
2. try to create a Page

Expected:
There should be a way how to embed an image, for example via a file picker that would allow me to copy the link to the image in the draft area.

Happens:
There is no way to embed an image.

This breaks backwards compatibility (this feature existed in 1.9) and makes File API completely unaccessible via any other way than TinyMCE + FORMAT_HTML. Or did I overlook something and there is an obvious way to do it?
