Default to base_path if SCRIPT_NAME not set for tracd

[mail+trac@…]

I'm not sure if this is an issue with the deployment at Dreamhost PS w/ the domain proxy, but this is a work-around that could prove useful in other situations, too.

Setup: domain.tld/project => proxied to localhost:8000

Then, starting standalone tracd as follows:

$ tracd --base-path=/project -e ~/trac

SCRIPT_NAME in BasePathMiddleware? is unset, so all requests go to /<project> instead of /project/<project>

This patch fixes the problem by defaulting to base_path if there's nothing better available:

Interesting, thanks for the patch!
