[x3d-public] X3DJSONLD (less vulnerable now).

[John Carlson]

One good thing I'd like to report is that I'm getting around 
difficulties with the node-java 0.12.2 node.js module by using 
process.exit(0) at the end of the program.  Woohoo!  I suggest that this 
be added to X3dToNodeJS.xslt.  I can provide a patch.

Also there are no more vulnerabilities in X3DJSONLD's dependencies (code 
is checked in).  There may be issues with programs that use node-java, 
but I'm going to start tracking them down.

Here are some files with process.exit():

./lib/stylesheets/X3dToNodeJS.xslt
./node/json2all.js
./node/NodeSerializer.js
./node/xmldiff.js
./node/jsondiff.js
