COLDBOX-246 autowire proxies

https://ortussolutions.atlassian.net/browse/COLDBOX-246

Automatically autowire remote proxies so they can automatically take advantage of mixins and AOP. Since "this" in a super class's pseduo constructor is a reference to the super class and not the sub class, use the cgi.script_name to determine the path of the proxy and get the metadata from there.
