Changed the resource type API to create AST objects rather than directly instantiating resource types. This allows the same code paths to be used to handle the results of parsing both .pp and .rb files. This makes .rb files work properly in multiple environments, because the types are now instantiated by code that is aware of which environment the compilation is happening in. It also reduces the risk of future changes breaking .rb file support. Also, switched to using "instance_eval" rather than "require" to evaluate the contents of the .rb file. This ensures that if the file has to be recompiled (because it became stale), it will actually get re-evaluated. As a side benefit, ResourceTypeAPI is now a class rather than a mixin to Object, so its methods do not pollute the global namespace. To reduce the risk of customers coming to rely on implementation details of the resource type API, changed its methods to return nil, and removed methods from it that were misleadingly labeled as "private".
The loop detection mechanism isn't great (it should, for example, allow nesting if the signatures differ) but the key problem was that the ensure was simply backwards.

That's it. Now its got the same name internal or external.
This mostly modifies autoloading to look for files ending in either 'pp' or
'rb' using Dir globing with {,.pp,.rb} or .{pp,rb} as appropriate. It could
easily be extended to add support for other formats (e.g. xml) by adding them
to the globs (though, if this were to be done often, having a centralized list
of supported extensions would be a good (and easy) refactor).

Also changed the internals - we're no longer using Resource instances with the ruby block, instead we're using a simple new class. We had to do this because Resource has too many methods - e.g., 'file' returned the file name rather than created a new resource type. Signed-off-by: Luke Kanies <luke@reductivelabs.com>
