allow cards without names

Idea

 

Sometimes you want to create a card, but don't want to have to name it:

  • Pointers where each item has multiple elements (e.g. image & caption; recipe ingredients; for ICAH's Resources it would be nice if the files didn't have to be named)
  • very short items (e.g. tweets don't have names, some blog systems also don't require it)
  • uploading images/files (auto-naming of those cardtypes will help a lot)
  • ??

This is probably a big design headache, so even if we want it some day, hopefully we can handle most such situations with add auto-generated cardnames.
