exp_adminui 1.0.0.44: the map field loads the Google Maps API only with an API key

• Fixed: The ezgmaplocation edit template of the adminui design loads the Google Maps JavaScript API only when [GMapSettings] ApiKey is set, from https://maps.googleapis.com with the key URL-encoded (it loaded it from maps.google.com on every edit form with a map field, also without a key, which an enforced Content Security Policy blocked). Without a key no map is set up, as in ezgmaplocation 6.0.12.
• Added: tests/expadminuigmapapikeytest.php (DB-less).
