support for long types for data-ports (e.g. copy/paste)

[franzlst]

A long is a very big integer and usually not used by common RAFCON users.

At the moment we have the problem that a port of type integer becomes a long (whithout that the type change only as value) while editing and if you wanna copy this state the new port is not accepting the long as int. Interesting to know, this state can be saved and re-opened, but can not be copied. This is maybe also the right hint to solve this issue.

So what is load state (most likely a json generated object) doing different compared to the copy method which both use the DataPort.__init__-method.
