encodings: shorter json names

["Gemmill, Craig" <craig.gemmill@tridium.com>]

I’d like to suggest using ‘nodes’ instead of ‘childNodes’, and ‘tag’ instead of ‘tagName’ in the JSON encoding.  This would be a shorter version that would convey the same meaning.

 

Also, if ‘tag’ is not specified, it should default to being ‘obj’.  This would further reduce the size for many cases.

 

Thanks
