Model Generator should use FQ class names

Hi all,

Model Class and Model Interface Generators should use fully qualified classname for persistent object getters.
For example, method signature:
public I_R_Status getR_Status() throws RuntimeException;
should be:
public org.compiere.model.I_R_Status getR_Status() throws RuntimeException;

In this way we can avoid a lot of classname complications faced in complex projects.
