Improved pom.xml and I2B2ODMStudyHandlerClientTest
- pom.xml dependencies: added jsoup and opencvs, removed httpclient and powermock.
- extended the I2B2ODMStudyHandlerClientTest class to use default values when the odmpath and/or exportpath environment variables are not set.
Merge pull request #3 from FreekDB/master
