JSON updates

Fixes in the JSON code:

• jsonToStream is now available for user objects: define a member function void jsonToStream(std::ostream &); and stream out your contents.
• Array and map generation for container types now need to be explicitly called out with makeMapFromContainer and makeArrayFromContainer. They work on all container and map types now too.

No functional changes from v1. Just a simple autoconf fix to get things building for me on the RC1 of GCC 4.9
