- fixes for bug: http://openmodelica.ida.liu.se:8080/cb/issue/1012

  Solving of linear system of equations generates incorrect results.
- the problem was the fact that continuous equations were classified
  as discrete and ended up in functionDAE_output2 which is never called
  during the continuous integration but only at events.
