changed: now Request class is a model class - we have fields() method there to map fields for ezc templates (currently only dir_tab)

removed: [dir_tab] ezc statement
changed: Ls winix function loads its own dir_tab container (beforehand it was loaded by [dir_tab] ezc statement)
         it's available by [child_dirs] name
