Subject: [PATCH] [New] Changed Parameter.getValue() for implicit cast to type

Now you can simplify:
StringParameter valueS = resource.getParameter("bagId", "paramId");
String value = valueS.getValue();

to:
String value = resource.getParameter("bagId", "paramId").getValue();

Casting is done implicitly, thus this can lead to runtime exceptions
when the parameter is not of the relevant type, but otherwise it reduces
the code by one line.

Setting the value in this manor is not supported due to the
ListParameters requiring a type of List<T>.
