Configurable Comment Block support

The generated MQ script contains a comment block at the top of the file. The content is configurable using the 'Comment template' property described above. By default, the extractor includes the generated script filename, generation date and time, Rational® model name, details on when the model was last saved and the version of the extractor used to generate the script. For example:
   
– Script Name: MQData_output_FTM Fragmentation Sample_20131015_132158.txt
– Generated: 2013-10-15 13:21:58 BST
– Model Name: FTM Fragmentation Sample
– Model Version 2013-10-07 17:06:28 BST
– Extractor Version: 2.1.1.0_v20131016
