Original Body: Instead of rolling our own, we should see if we can easily drop in the new Bunch package in place our our existing Bunch object. http://pypi.python.org/pypi/bunch/1.0.0

util.Bunch is useful not only internally, but also in apps, e.g. as substitute for not yet existing model objects when rendering forms. Beefing it up a bit can not harm.

TG 2.1 is already a rc, but we can consider this for TG 2.2. We should check if jsonification works properly and whether we should better incorporate this in our codebase, because it's so small and we already have so many dependencies.

Bunch code is actually short enough that in my opinion doesn't make much sense to add an external dependency to replace it. Also last Bunch release is 3 years old, so it didn't change much over time.
