Update jquery.uls and adapt styling

jquery.uls.compact module is kept for now as some other
extensions depend on it. But it does not do anything
anymore.

There are some styles which should be in jquery.uls
upstream, but given the current state that is easiest
done in a follow-up later.

The main change is that language selection is now
compact by default: no heading etc.

Includes style changes for the dialogs, and especially
for the new position of the callout caret.
