Subject: Integrated JSON extraction utility

The utility used in eos-english and eos-programming-app was integrated and installed as part of the SDK

CR comments addressed include:
 - Integrated new facilities available on GTK
 - Removed duplicate prototype declaration
 - Reformatted CLEANFILES var declaration
 - Used configure.ac to get @PACKAGE_VERSION@
 - Added version() and usage() utilities
