r19259: An ldb browser.

This has the layout complete so anyone interested can see what a qooxdoo
application might look like.  It doesn't yet issue any JSON-RPC calls to do
anything useful (that's next), and it still has the appearance of a qooxdoo
test rather than something unique to Samba.  I'll adjust the appearance later.

This layout is loosely (or not so loosely) based on 'gq'.  A few things in
this layout won't apply to an ldb browser, but they're there for the time
being anyway until I decide exactly what to do with them.
