Instead of a toggle, could we use some logic like:

- no selection: edit all clicked features
- selection, but no selected features exist where clicked: edit all
clicked features
- selection, where selected features exist where clicked: edit ONLY
these selected features

This way the "only edit selected features" behavior will only kick in
when a selection is in the area being edited. It should avoid the
annoying behavior where a selected feature on the other side of the
map becomes the editing target (move tool should probably use this
approach too!).
