Allow var() in content property #2700

What: The var() css function is now allowed in the content property.

Why: It is valid (and sometimes very useful!) to use CSS variables in the content property. Currently, Emotion throws and error (in development) when var is encountered, making its use impossible.

How: var has been added to contentValuePattern regex.

Could you just prepare a simple jsfiddle or something that would showcase how exactly you are using this with plain CSS?
