Fixed bug when checking for updates to an object (as opposed to an array)
Fixed memory leak - observed objects were hung on to even after calling Object.unobserve
Added test for object property delete then add
Added unit tests. All pass against Chrome 37. Might want to ignore the 'multiple' tests due to performance reasons, but it's important the aggregate ones work.
Removed unused require.js test stubbing.
