Fixed a problem where regexp would not work on path separators under Windows.
Fixed use of wrong logger library.
Changed ServerProperties.java to be an interface rather than an Enum.
Adpated ContextListener.java due to that change.
Added support sandboxed excution when using Windows.
Not fully funtional yet as IO of sandboxed apps is not forwared.
Have to look into that.
