Tests for URL functions in shlwapi

[Matthew Mastracci]

I've started on some tests in shlwapi.  I've added the following file to
the tests directory under shlwapi, but I can't include it in a cvs diff,
because I don't have write access to the repository.

Any hints as to diffing a new file cleanly w/o write access to CVS?

These tests compile and run clean with the last CVS tree I pulled (a few
days ago).  I need to flesh them out, but it's a start.

Here is the diff for the Makefile.in:
