Title: Add ref & refequals method for Php::Value

If you want get a reference of a value, you can use `ref` method. It will work correctly when patched #114.

You can use `refequals` method to check for reference equality. You can use it to compare whether two arrays are the same. There is no similar function in PHP, but we need it when we want to write a serialize program.
