Need "metaprog" entry ni the dsl file created with the wizard

[ebousse]

I believe that the file https://github.com/eclipse/gemoc-studio-execution-java/blob/master/java_xdsml/plugins/org.eclipse.gemoc.execution.sequential.javaxdsml.ide.ui/templates/SequentialSingleLanguage/$languageFileName$.dsl

should contain the line:

metaprog = org.eclipse.gemoc.metaprog.kermeta3
