Changed/fixed the way Django handles SCRIPT_NAME and PATH_INFO (or

equivalents). Basically, URL resolving will only use the PATH_INFO and the
SCRIPT_NAME will be prepended by reverse() automatically. Allows for more
portable development and installation. Also exposes SCRIPT_NAME in the
HttpRequest instance.

There are a number of cases where things don't work completely transparently,
so mod_python and fastcgi users should read the relevant docs.

Fixed #285, #1516, #3414.
