DefaultStatusActions / localize message (#160).

* Localize email and status message using strings.xml and StatusValueDes
* Formatting
* LangUtils / Add translation method to retrieve translation eg.
  * LangUtils.translate(context, "statusUserEdit").get("eng") to retrieve statusUserEdit from strings.xml
  * LangUtils.dbtranslate(context, "StatusValues", Params.Status.SUBMITTED).get("eng") to retrieve submitted translation from StatusValuesDes table
* Change property visibility to protected (useful when extending the DefaultStatusAction).

To be improved:
* URL for listing status search should depend on the UI (#162)
