Swinlanes: Added support for Pools and Lanes on Activiti Modeler.
Based in Activiti Designer, I added the process attributes in the Pool object and stencilset. This means that the pool attributes, such as ProcessRef, Name and Executable, will be used to compose the Process object.
Changed logging IOException to the configured logger. Printing stacktrace may not be optimum.
