[#33] Updated stuff for running automated integration tests...
 * Added command line option for specifying a properties file
 * Created properties files for development and integration tests (they are all the same currently.  this needs to be changed).
 * Updated the gradle build to allow for specifying a properties file.  Currently you can specify a development properties file, integration test properties file, or the default properties file.
 * Created script that can be used to run the integration tests.
