Miscellaneous improvements for using this as a git submodule

[johslarsen]

I have been using your testing framework in some of my personal projects for years. I have it as a git submodule that I drop into the repository of a project, but since the only repository I found when I initially downloaded it (v1.5) from SourceForge was a CVS repository I created my own git repository and added the source code as its initial commit. When I published one of my projects on github it had this testing framework as a submodule, so I also published my "fork" of this project on github. And as I value attribution I had written your name and mail address, which happens to link to your account, as the author of the initial commit in the testing framework repository. Looking at the log of my newly created testing framework repository your user was automatically attributed the initial commit, and when I looked at your account I found this repository, so I recreated my testing framework repository with your repository as its basis. Over the years I did some small changes to the code base, so that it was easier to use as a submodule, and as they do not break anything I thought I would offer them to you, along with my gratitude for creating a minimalistic testing framework that can be dropped into any project and made working by adding a few lines of code to its Makefile.
