	Checker.py 
Log Message:
Added permission attribute for service directives. This lets you set
security within the service directive itself.

Added a __Security_checker__ attribute, checked by the ProxyFactory
that specifies a checker to be used for proxies. This allows us to
record the permission requirements on a component without actually
creating a proxy. If this attribute can't be set, we'll go ahead and
create the proxy anyway.
