Work on normal task EXT-3636 (Code Improvements: Voice control panels - Make Voice states and fade timeout xml driven)
-- made Avatar Item Voice States xml driven. Added fake xml panel file with one textbox per style.
  Style of the appropriate textbox is applied to avatar item's name
-- It was necessary to change visibility of the LLTExtBase::getDefaultStyle() to public.
