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.
