make simple edit-alternative to double click+solution

We ended up with refactor card menu - the menu that pops up from the little gear/cog to the right of any card name in open/closed view (and it can be added to most(?) other views with "show:menu"), vaguely similar to #2 below.

Two Earlier possibilities:

1.

Cards in any view (that has card slot info) other than open or closed can be triggered to show the title bar - but translucent - over the top of the card's content.

The trigger could be hovering over the card for a second or so, or clicking on the card content (hrm, that wouldn't work for cards with content that already have a behavior when clicked, e.g. collections with item:link or any text type with only a link as content). Could offer both...

In any case, if the user clicks on the faint title bar, the card's view changes to open - the content slides down, the title bar becomes opaque, and the footer appears at the bottom. If they click on a control in the faint title bar, the click could be processed directly. If we do this, could also have a faint footer appear - this would make for one-click card watching.

If they click View, it goes back to its original view.

Note that this only happens if the card's "+*edit controls" points to "hover" (or "click" depending on how this is triggered). *all+*edit controls defaults to this method being on, and "double click" being off. See Ability to disable double-click-to-edit.

2.

A small interface like this:

...that can pop up whenever you hover over an inclusion not in open/closed view, perhaps just offering an edit link for now, but to which we could later add the "More..." menu, which can offer View, Changes, Options/Settings, Related, and from card footers: "Cards" (maybe "Parts" is a better term for this?) with a submenu showing those links, "Last Editor: |name|", and the "watch" link.
