membes 1.0.0-alpha6

Sixth alpha: the member directory is verified against a live Membes account.

• Location-based directories. When a Membes directory uses radius search, the search form now requires a location and always sends it; an address Membes cannot find is reported to the visitor instead of failing.
• Cleaner results. Address parts that Membes returns as the text "null" are dropped, and an empty search shows Membes' own message once instead of twice.
• Profile pop-up. Scripts and stylesheets in the member's Membes profile page are removed before display, and the member's name and address keep their headings.
• Tests now use real Membes directory responses as fixtures.

Not yet verified against live data: the map view, Excel/PDF exports, and multi-value filter semantics.

Upgrading from earlier alphas is not supported: uninstall and reinstall.
