Title:
  refreshing a song list is slow

Status in OpenLP - Worship Presentation Software:
  New
Status in OpenLP trunk series:
  New

Bug description:
  When changing song title / adding new song / removing new song / edit
  the song lyrics - whole list is refreshed and it is slowness is
  noticeable already with a few thousand songs.

  We should find a way how to improve that.

  Probably by using more advanced features of tables from Qt4 where we
  would not update the whole song list but just a part of it.

  Probably some inspiration could be found in code examples to pyqt
  book:  http://www.qtrac.eu/pyqtbook.html
