[PDI-12204] - Transformation Executor issue with main output and result rows - removing i18n resource's duplication

In fact, TransformationExecutor did not work so far, thus it was re-implemented due to Jen's requierements (see ticket's description http://jira.pentaho.com/browse/PDI-12204 and this comment http://jira.pentaho.com/browse/PDI-12204?focusedCommentId=188869&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-188869).

Also, please take into the account UI is not displaying "preview" table correctly and it is temporary affordable (http://jira.pentaho.com/browse/PDI-12204?focusedCommentId=189561&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-189561).
