Make nova work even when user has LANG or LC_ALL configured

  
  Some commands are having different results when used in another language environment.
  For example ifconfig output parsing fails in my language.
  Also unittest using cat failed, as it didnt expect czech language in the error message.
  
  This small patch makes it work.
  Also adding myself to 'Authors' file.
