inclusion syntax for items and more+solution

Deprecate view:card and view:line in favor of view:open and view:closed. Also, make the "view:" optional - i.e., interpret |open, |closed, etc. the same as |view:open, |view:closed, etc.

For nesting of cardlists (Searches and Folders/Holders/Pointers), add:

  • item:open
  • item:closed (this is the default)
  • item:content
  • item:naked
  • √item:link
  • √item:name
