Updated eJSON to use Eiffel 6.8 version.

Basically the changes are:

Replace ? by detachable
indexing by note
removing `is' from features, and in some places replaced by =
In the ecf now we need to include every gobo library, because the gobo.ecf, exclude libraries that are needed.
TODO: the test-suite is not void-safety.
