Null and false values are incorrectly binded

[schtr4jh]

Hi everybody!

First of all, great job developing vue.js! I'm really impressed with it and it will definetly be one of must-use libraries in future web projects.

However, today I (or @jackmcdade actually) experienced some issues with incorrectly binded (at least) null and boolean values. Issue occurs for staticly binded and newly added values. See fiddle for more details: https://jsfiddle.net/df4fxhqy/10/ .

Is there something that we're missing and should know about?
