No easy way to compare two objects

[maxandron]

Hi,

It's more of a feature request than a bug, basically you can't compare two JsonObjects

For example:

class Foo(JsonObject):
     bar = StringProperty()     
a = Foo(bar="wow")
b = Foo(bar="wow")

>>> a == b
>>> False

I don't mind pushing a pull request if you agree that this would be a useful design for the library
Thanks,
Ron.

P.S.:
Currently I compare like this:
json.dumps(a.to_json(), sort_keys=True) == json.dumps(b.to_json(), sort_keys=True)
