[code-review] Apache::MVC

OK, it's a bit of a big one (530 lines) but I think it'll be an exceptionally
useful module once it's done. I sent version 0.1 of Apache::MVC to CPAN, and
you can find it at http://search.cpan.org/~simon/Apache-MVC-0.1/
along with some documentation about how it's supposed to work.

Answer to the obvious question: Yes, it doesn't necessarily have to be
CDBI/TT/Apache based, and over time it will become generalised and Apache::MVC
will be replaced by a subclass of CleverProjectName that knows how to talk to
Apache.

The first thing I'd like to know is whether or not the documentation is clear
enough about what it's actually *for* and how to set it up; I plan to write
some more documentation about how to subclass it to do what you want.

After that, any comments on the code would be appreciated.

Many thanks,
Simon
