- Fixed crashing bug when name and class were empty for a docked app.

- Removed MIN() and MAX() macros and replaced them with WMIN() and WMAX() from
  WINGs.
- Added a hint that Window Maker crashed, to allow windows to be placed
  in their correct previous positions after a crash situation and also to
  preserve their state before the crash (minimized, shaded, hidden, ...)
