Extension configs should go into their own directory

/manifest/extensions/ or /manifest/config/extensions/ ?

From Nick Dunn:

Looking into my current /manifest I see extensions.xml and extensions.sample.xml in the root folder. Since each extension stores its config as a separate XML file, should these go into an "extensions" folder?

From Alistair:

extensions.xml is not a config file per se. It is a system file for holding extension status and delegates. I don't think it should not be in `/conf. If it was, there would need to be special rules in the core code to ensure the Configuration object didn't accidentally try to load it in.
