Fixing dependency system for javascriptresponses. In particular, adding a location for node-only packages (that are never sent to the client) in lms/lib/node_modules and adding lms/static/js, lms/static/coffee/* to the NODE_PATH, along with the course's data directory.

+/*
+  I've wrapped Makoto Matsumoto and Takuji Nishimura's code in a namespace
+  so it's better encapsulated. Now you can have multiple random number generators
+  and they won't stomp all over eachother's state.
+  
+  If you want to use this as a substitute for Math.random(), use the random()
+  method like so:
+  
+  var m = new MersenneTwister();
+  var randomNumber = m.random();
+  
+  You can also call the other genrand_{foo}() methods on the instance.
+
+  If you want to use a specific seed in order to get a repeatable random
+  sequence, pass an integer into the constructor:
+
+  var m = new MersenneTwister(123);
+
+  and that will always produce the same random sequence.
