only show simple relative inclusions in forms
Ticket
+issues
showing absolute inclusions in forms is confusing -- it tempts users to re-edit the same card over and over again in contexts where it appears to be, well, contextual (and therefore a different card each time).
+solution
implementation is as simple as a little regexp tweak in #edit_slot (unless we find out this has unwanted consequences. Still somewhat concerned that there may be non-simple relative inclusions in play in structured editing somewhere)
+example
This ticket was originally about CSS (see italicized text below). I'm proposing we solve that problem and others by having forms only handling inclusions beginning with "+".
If you look at the HTML of http://test.dwagn.org/new/type_with_simple_inclusion_in_form you'll see that the simple included card "Menu" has the CSS class "RIGHT-menu".
Should be "SELF-menu", yes?
