Bypassed the parsing of language strings in df_translate() if there are no parameters passed.  THis is to fix an issue with translation of actions that include PHP expressions.  The translation was stripping out the expressions before it gets to actually parse the action.
Added feature to allow language tool to ignore parameters in translations.  This was necessary to allow translation of actions labels and descriptions that contain their own parameters.  This way the parameters can be passed through directly.
Merge branch 'master' into 2.0.x
