handle card creation when can't create Basic
Ticket
+issues
Setup: Anyone doesn't have permission to create Basic, but does have permission to create one or more other cardtypes.
If you go to /new/card you're told you have to sign in first. If you go to /new/AllowedCardtype you get an offer to create a card of that type, with the right edit interface.
If you go to wagn/NonexistentCard you get an offer to create a card, with the type menu showing types that Anyone has permission for. However, you get the Basic edit interface rather than the multi-edit you should get when the menu shows a type with a hard-format.
Either we want going to wagn/NonexistentCard to tell you that you have to sign in first, or to generate the correct edit interface for whatever type is selected.
+solution
I think we only want to offer the edit interface at all if (a) a type is specified that a user has permission to create, or (b) the user can create basic cards.
In other words, if an anonymous user who can only create "Fruit" cards clicks on a red "Canada" link, he should get a denial, not a fruit interface.
