Add "Reparse Qbs (Force probes)" to project context menu

I often go to Project tab in Qt Creator to tick "Force probes" and then untick it after I see it started the reparsing. It would be much more convenient if the option to force probes was already in the context menu next to current "Reparse Qbs". Beside the convenience the force-probes sometimes triggers infinite loop until the option is unchecked. Re-running it with this option (Force probes) exactly once would help mitigate this issue.
