anubis upgraded to 1.21.3, all services use metarefresh now

[Mark Wielaard]

Hi,

Anubis has been upgraded to 1.21.3 (from 1.20.0).

All services now use the metarefresh (non-javascript) challenge method
for generic browsers. The metarefresh challenge seems as effective as
the java-script challenge and should work for more people.

Please report if this isn't working for you.

Cheers,

Mark
