referencing current card and parts in inclusions+issues

Need a way to reference current card and it's parts in inclusions,

also, these bugs are related:

_self|view:name breaks multi-edit. It offers you to edit the named (formatted) card, which of course gives permission denied when you save. Example below.

base:parent (the old syntax for _left) breaks badly if used on a simple card. This should be fixed, and simple cards should be handled at least somewhat elegantly when implementing _left and _right (maybe replace "Add " with some light red text describing the problem, i.e. "_left [or _right] has been used, but is not a plus card."). No example, because it busts Recent Changes too, but if you have a card foo including +bar|base:parent then you get this error:
