Introduced the possibility for States to transform/modify input before the data is added to FLYSArtifact.

+
+	* src/main/java/de/intevation/flys/artifacts/states/DefaultState.java:
+	  Added a transform() method. This method should be used to transform
+	  input data in form of a string into a better data structure. This state
+	  provides a simple implementation which just returns a StateData object
+	  that contains exactly the input string.
+
+	* src/main/java/de/intevation/flys/artifacts/FLYSArtifact.java: Transform
+	  input strings using DefaultState.transform() before they are added to
+	  its data pool.
