cgi-mechanize.t: test case for subplaces like "Mahlow-Waldblick"
beta cgi: fix for subplace support

Sometimes subplaces like "Mahlow-Waldblick" were matched (e.g. in
init_plz()), but sometimes not (e.g. with the $outer_berlin_qr
regexp). Now the latter situation is fixed by the new regexp
$outer_berlin_subplaces_qr.
