1.6 to please indigo
version numbers, solve warnings, put JSON classes in one place
Moved Scion client source from INTERNAL/java/src to src.
Implemented the new JSON protocol.

Also experimenting with compilation error markers, but this is done from the wrong place, so they tend to disappear again.
Added JSON Simple library.
forgot to add some classes
