- added WMRemoveFromArrayMatching(array, match, cdata), which will remove the

first element in the array that is matched by match(item, cdata)==True.
- added WMArrayFirst(), WMArrayLast(), WMArrayNext() and WMArrayPrevious()
  functions and also WM_ITERATE_ARRAY() and WM_ETARETI_ARRAY() macros, to make
  interfaces to WMBag and WMArray similar and to make life a little simpler
  when iterating through all elements of an array.
- replaced bags with arrays wherever appropriate. This will improve
  performance a bit.
- replaced some recursive code with iterative code in WINGs/selection.c
- some code cleanup is src/

WINGs/wview.c
