Additions to CFURL and CFBundle

I propose a few additions to CFBundle and CFURL APIs. Not sure how general they are, but they would be nice to have out of the box.

The `CFURL::absolute_file_url` test is a bit big, but it demonstrates the need for `CFURL::absolute()`.

I think `CFBundle::main_bundle()` should return an `Option` since `CFBundleGetMainBundle` can return NULL but that is a breaking change and I decided not to include it.
