mod_adhoc_dataforms_demo: Add compat with 0.11 (vs trunk api change) The name of the "access for anyone" permission level changed from "user" in 0.11 to "any" in 0.12/trunk to make it clearer that it's basically unrestricted. This is unfortunately not backwards-compatible. Thanks to Sam for stumbling upon this during a demo.

to any local user and receive their presence in response, bypassing
