mod_compat_roles: New module providing compat shim for trunk's new role API The new role API is translated to is_admin() calls on older versions. On newer versions (which have the role API) this module does nothing. It allows modules to drop their use of is_admin() (which is not available in trunk) and switch to the new role API, while remaining compatible with previous Prosody versions.

This module sends `-- MARK --` to the log once per minute. This may be
useful to give a sense of how busy the server is or see that logging and
timers are still working.
