mod_http_oauth2: Add role selector to consent page List includes all roles available to the user, if more than one. Defaults to either the first role in the scope string or the users primary role. Earlier draft listed all roles, but having options that can't be selected is bad UX and the entire list of all roles on the server could be long, and perhaps even sensitive. Allows e.g. picking a role with fewer permissions than what might otherwise have been selected. UX wise, doing this with more checkboxes or possibly radio buttons would have been confusion and/or looked messier. Fixes the previous situation where unselecting a role would default to the primary role, which could be more permissions than requested.

# Groupchat 1.0 usage statistics gathering

Groupchat 1.0 was probably the protocol that predated
[XEP-0045: Multi-User Chat] and there is still some compatibility that
lives on, in the XEP and in implementations.

This module tries to detect clients still using the GC 1.0 protocol and
what software they run, to determine if support can be removed. 

Since joins in the GC 1.0 protocol are highly ambiguous, some hits
reported will be because of desynchronized MUC clients

# Compatibility

Should work with Prosody 0.10.x and earlier.

It will not work with current trunk, since the MUC code has had major
changes.
