Add ability to toggle notes section of all cards open and closed

[christopherbot]

It may be desirable for the user to be able to toggle whether the notes are displayed for each item. For example, if they simply want to see the items in a more compact manor, they should be able to click a button to collapse the cards into a more compressed state.

Some more thoughts here:

Compact view (only list items are displayed, not their notes):

GROCERIES   [ (C) D ]
+-------------------+
| Apples        [ ] |
+-------------------+
| Oranges       [ ] |
+-------------------+
| Pears         [ ] |
+-------------------+
| Grapes        [ ] |
+-------------------+

Detailed view (list items with their notes):

GROCERIES   [ C (D) ]
+-------------------+
| Apples        [ ] |
| 4 Honeycrisp      |
| 4 Gala            |
+-------------------+
| Oranges       [ ] |
| 2                 |
+-------------------+
| Pears         [ ] |
+-------------------+
| Grapes        [ ] |
| Red AND green     |
| 2 of each         |
+-------------------+

What if long-pressing on a card when in the compact view made just that card pop out in the detailed view for as long as the press is held?

GROCERIES   [ (C) D ]                GROCERIES   [ (C) D ]
+-------------------+               +---------------------+
| Apples        [ ] | <- Long Press | Apples          [ ] |
+-------------------+               | 4 Honeycrisp        |
| Oranges       [ ] |               | 4 Gala              |
+-------------------+               +---------------------+
| Pears         [ ] |                | Pears         [ ] |
+-------------------+                +-------------------+
| Grapes        [ ] |                | Grapes        [ ] |
+-------------------+                +-------------------+
