Updated dependencies to latest version

* except junit (incompatibility with powermock)
* quartz (more work needed)
* unit tests are working
* clean up scope to ensure direct dependencies are declared, dependencies not directly used are in "runtime" scope

Also added maven sortpom plugin to ensure pom is in a consistent order (which make merge easier when changes are done to the pom).

Also added myself as a developer (I think I earned it ...)
Merge pull request #202 from jmxtrans/update-dependencies
