revert 68495 and all subsequent "toolbar refactoring" (rewriting) commits because they broke toolbar use for everyone.
in the future, rewrites like this MUST be submitted as PATCHES, not direct commits. this allows application authors to continue having fun writing code without suddenly having broken widgets.

I have left the newly committed edc, as it does not seem likely to cause issues on its own.
