Select items by clicking the card instead of copying them

Copying was a side effect of a click, which made it impossible to build
a selection with the mouse and surprising when the intent was to pick
something up rather than copy it immediately. A click now selects (or
deselects), and copying is an explicit action from the selection bar or
the right-click menu.
