Many updates

- Exit warning dialog is now based on standard NSAlert
- All command-line tools are executed asynchronously using
  NSOperationQueue
- Status is processed using XSLT and visualized in basic HTML format

Also, all constants for command-line tools are moved to wscipt/config.h.  If
new commands needed, they should be added into wscript, which will
eventually create proper config.h file.
