Brian Ashworth 583ceff6f6 swaybar: hide mode visibility improvements
This allows swaybar to become visible when the mode changes (to any
mode other than the default). swaybar will be hidden again when the
modifier is pressed and released or when switching back to the default
mode.

This also applies the same logic to visible by urgency to hide swaybar
when the modifier is pressed and released.

These changes are to match i3's behavior.
