Relocate Configure::load() out of bootstrap

[ProLoser]

Paths are not needed anywhere except in the datasource, and if you don't load the datasource or component you don't need hosts loaded either.

Expecting users to add these to their bootstrap creates an unnecessary overhead both to the app at runtime and to the developer for getting the plugin working.

The main reason why it's here is because it's difficult/impossible to test, but I don't feel this is a good enough reason to structure the code this way.
