Major change:
   - Fix AliOnlineReco.h exit (useful for alionlinemonitor)
     Problem:
           the user must select each started process from AliOnlineReco and than click Stop button before clicking on Exit (or closing window from x button). If by mistake he does not do this in this exact way, child processes become zombies.
      Fix: clicking on Exit button or X window button will exit AliOnlineReco (and kill all started processes) without needing to select and stop each process.

minor changes:
   - Fix a few comments, indentations & look of code
