Progress summary: Forward click to "current" progress details.
It was annoying that it wasn't possible to click on the summary progress bar to e.g. open the compile output or issues pane, even when you had only a build running. This change forwards the click to either the progress that currently shows a details widget in the status bar (like the build errors/warnings from the build progress), or to the last progress that was started.
