CLSQL Co-maintainer

I'm very pleased to report that Nathan Bird has joined me to co-maintain CLSQL.
Nathan is sponsored by the fine folks at http://www.acceleration.net/programming/
and has nicely reworked the test suite and added other cool functionality to CLSQL.
Some of those changes are already in a released version of CLSQL, some are in the 
current git repository, and he has more awaiting integration.

One change to the git repository is that there is now a development branch in addition
to the master branch. If you wish to follow the development branch, then in your CLSQL
git repository give the command:
  git checkout --track -b development origin/development

You can then switch back and forth between the master and development branch with the
commands:
  git checkout master
  git checkout development

I'd like to publicly thank Nathan for his great contributions and his willingness to
help further maintain CLSQL.
