ResourceLoader namespace (attempt 2)

Move ResourceLoader classes to their own namespace. Strip the
"ResourceLoader" prefix from all except ResourceLoader itself.

Move the tests by analogy.

I used a namespace alias "RL" in some callers since RL\Module is less
ambiguous at the call site than just "Module".

I did not address DependencyStore which continues to have a non-standard
location and namespace.

Revert of a241d83e0a6dabedf.
