links to stdlib modules

[Glyph Lefkowitz]

L{socket.AF_INET} could link to http://docs.python.org/library/socket.html#socket.AF_INET.

L{os.path.join} could link to http://docs.python.org/library/os.path.html#os.path.join

This link scheme isn't always accurate, but it's pretty consistent and it's accurate often enough to be highly useful. pydoctor could find the 'os' and 'socket' modules programmatically, it doesn't need to have a builtin list, and all the stdlib stuff goes together, so by using one stdlib module's __file__ as reference, it could be quickly determined which things could be linked to in this way.

http://python.net/~mwh/attr-doc/twisted.internet.base.ThreadedResolver.html has a go at this.

I cleaned up the code a bit and pushed it to trunk.
