newer patch from Alex

[bill]

TitlePane? isn't classified as a layout container, moving test to misc/. Not checking in yet though because these tests are getting failures against latest code.

I haven't checked this in yet because it's still getting failures against the latest code (even with the Button checkin that Doug did).

MenuItem? tests should be using textDirNode and not focusNode

And looks like the other problem is that the update for TitlePane?.js is missing.
