Always show hint in text entries, even when they have focus.

It was impossible to show the hint for the initially focused child of a dialog
before, as the hint was hidden from the very beginning. By showing it always
we avoid this problem.

We may want to add an option/flag for SetHint() to make this configurable
later if somebody really needs to show hints only for as long as the control
doesn't have focus.
