eval & uneval

uneval is disgned to be similar to uneval but works cross browser. uneval is similar to uneval, but there are few difference:

1. uneval currently do not support some types such as Error.

1. uneval will convert native function to "null".

1. uneval will format codes differently from uneval.

Warning

Although, uneval is designed to output source with no side effect. But there may be some bugs or limitations in the code. You should avoid using uneval any untrustable objects (maybe from user input) then eval it. NEVER use eval unless you know what will happen. USE AS YOUR OWN RISK.
