Simplify Pipeline pass management

Originally I planned to use Pipelines to bundle objects with effects like
environmentally mapped reflection.  However, that task was delegated to
effects themselves recently, so there's no longer need for passthrough
rendering in Pipeline.  The render_all function was also a nuisance, as
it required Pipelines to be treated differently from other Renderables.

Passes are now stored in a list instead of a map.  This allows multiple
passes with the same tag (think multipass lighting), and avoids the need
to store the pass order separately.

Move PipelinePass inside Pipeline and make the data members private

It's really simple and specific to Pipeline, so it doesn't make much
sense to have it as a separate class.  Encapsulation is necessary for
some future plans, and also more consistent with other public interfaces.

Constructing tags mostly happens when loading datafiles or otherwise
outside the rendering loop, so the small extra overhead from a
cross-library function call is not significant.  Renderables that wish to
compare the Tag against a fixed value should avoid constructing the
reference Tag on every render call anyway.
