Two more changes to BListView:

Browse Source 
* fixed handling of B_HOME and B_END in extend mode for multiselection, such that
  now all the items inbetween the anchor and the final target are selected, too
* made sure that the anchor always gets adjusted in _Select(), as otherwise
  navigation via cursor keys could get "locked".
