Reviewed by Joseph Pecoraro.

It's time-consuming to change a breakpoint's auto-continue setting through the
breakpoint editor popup. This patch enables the user to toggle between enabled,
auto-continue, and disabled by clicking on the breakpoint wedge in the sidebar
tree and in the source text editor gutter. The auto-continue option is only
cycled when the breakpoint has associated actions.

Clean up the breakpoint editor dialog so it hides irrelevant options when
no breakpoint actions have been added.

Automatically unset auto-continue when the last breakpoint action is removed.

Rename the delegate textEditorBreakpointToggled to textEditorBreakpointClicked, since
the behavior of the click depends on breakpoint state not available in the text editor.
