Bug 33297

Add Qt Bot to the list of "core builders" (builders which block the commit-queue when red) http://trac.webkit.org/browser/trunk/WebKitTools/Scripts/webkitpy/buildbot.py#L47 This is a master bug for tracking reliability issues (aka flakey tests) with the Qt bot which block us from adding it to the list of builders which block the commit-queue and cause "bugzilla-tool land-diff" to error out when people try to land (unless they pass --ignore-builders). The Qt bot seems pretty stable, so maybe it's time to add it to the list. If we encounter any flakey tests with the Qt bot, we can relate them to this bug. I think I'll code up a patch to add Qt to the list of core builders tomorrow unless I hear objections from folks.
