[#290] using bundler

* following setup instructions from http://gembundler.com/rails23.html
* adding generated files to .gitignore and .hgignore
* removing config.gem calls
* adding Gemfile that should work with all supported dbs and interpreters
* removing work-around for rubygems 1.5 deprecation. this seems to be fixed since now bundler handles the gem loading
