It doesn't make sense to show it there, since the "delete"
action has no effect, the "edit" button only collapses (useless),
and the thumbnail duplicates.
Wasn't parsing data-editor attrs correctly.
Using proper instances of the underlying editor now,
instead of relying on "active editor" states which get
wonky once they lose focus (e.g. when opening a dialog).
Periodically check for inline changes when focused,
since TinyMCE's onChange only fires on certain actions
like inserting a new paragraph, as opposed to any user input.
This also works around an issue where the "save" button
wouldn't trigger if the click is the cause of a "blur" event
after an (undetected) inline change. This "blur" causes onChange
to trigger, which will change the button markup to show "alternative" styles,
effectively cancelling the original click event.
Inside mediaform updateFromEditor we called $(this).updateFromNode, but this wasnt
pointing to anything useful after a refactor, which resulted in the fields not
being filled in with current data when editing an already-inserted image
Otherwise some non-textual changes such as moving images and resizing
them could be missed when saving.
This is because TinyMCE does not treat the image move/resize as an
undolevel and does not register this via regular "onChange" event.
Makes the editor API more flexible by triggering generic JS events that
can be used from entwine. This makes it easier to add event handlers to
the editor and cleans up the initialisation call from unrelated code.
The patching code also forwards editor changes to the textarea field,
which in perspective will allow the changetracker to react to changes in
this field as they happen.
Delayed show because TinyMCE calls hide() via
setTimeout on removing an element,
which is called in quick succession with adding a new editor
after ajax loading new markup

Space delimiter is often confused by browsers, and encoded as %20 which
breaks the shortcode system. Change to comma delimitation has already
been implemented, this is a followup cleanup.

Functionality that affects the values in the form better fits in
updateFromEditor function, where we expect the form to be modified.
Redraw should only affect visibility parameters.
Also added a more robust reset code, so we can always expect to get at
least a clean form, and re-added missing "target" checkbox.
Returning a link type "internal" in the situation when no link has been
detected is confusing and makes it hard to know downstream if the link
was detected or not. Switched that to null.
Also added target option to file downloads, as we don't currently have a
mechanism to default this field to "yes" for files.
