UI: reorganize proportional editing options

- Move connected & projected into individual toggles.
- Top-level proportional editing button now only toggles.
- Use popover for proportional edit-mode falloff and options.

Note that it's no longer possible to toggle connected via key bindings,
although this could be supported again if it's needed.
