Provide updating button for "what to show" button on CodeHolder, similar to Squeak 3.8 behavior. This button activates a menu, and displays the resulting menu selection. For the default look, normal buttons are rounded and the menu activation button is square (vice versa if the "Rounded Button Corners" preference is disabled). When menu selection is changed, the button label displays the selected mode ('source', 'decompile', 'bytecodes' etc).

I uploaded three packages to the inbox for review. These add a couple of hooks to ToolBuilder to teach an action button to react to "changed: #contents" notifications from a browser, and to allow showing a visual cue that distinguishes a menu activation button from an action button. As implemented here, the look and behavior is similar to pre-toolbuilder Squeak (although a nice graphical icon in the button would be a nicer visual cue than the old square versus rounded corners cue, help welcome here).

Comments and review appeciated, and if no objections I'll move this to trunk a few days from now.
