Title: Change variable scope in Dispatcher to allow better extensibility

I wanted to extend the `Dispatcher` class to add logic that converts underscore urls to camelcase, as well as modification of some default behavior, but because variables and `getFileExtension()` method were `private`, I could not extend it without basically rewriting the entire thing. So I modified the scope to be a bit more friendly to extending.
