+ Abstract out capturing stdout/stderr into a new OutputCapture class for re-use among the various unit tests.
+ https://bugs.webkit.org/show_bug.cgi?id=31870
+
+ * Scripts/modules/commands/queries_unittest.py: Use the new class.
+ * Scripts/modules/multicommandtool_unittest.py: Ditto.
+ * Scripts/modules/outputcapture.py: Added.
