Hit cloning

[robertvazan]

My hit processing pipeline sometimes needs to send the same or slightly modified hit to another property. I could use correct public implementation of the clone() method on GoogleAnalyticsRequest that would return T.

Added deepClone which returns new instance of same type. Didn't want to use standard clone as it returns object and users would have to type cast again.

AFAIK, Java allows you to narrow return types in derived classes. You can override it as public T clone() even though Object declares it as protected Object clone() throws CloneNotSupportedException.

Looks like it would work. So I will rename deepClone to clone and implement Cloneable
