Use java 1.7
Start and stop commands, runtime directory

* Add scripts.d/start.py and scripts.d/stop.py, including a simple library.
* Implement the start and stop commands.
* Add support for service parameters on the command line.
* Added the runtimeDir config option and command line option.
* Updated the help text to reflect the real world.
* Use stderr to print error messages.
* Removed the service coordinate parameter.
* Removed unused imports.
* Changed parameter parsing; using a list of parameters with no
  enforced structure on the service's parameters. This simplifies
  the whole structure quite a bit.
