#20 return exit code

[Silicon]

OptiPNG return the same exit code if the operation sucess or if do not (errorlevel=1).

The MS-DOS estandar is return exit code = 0 if the program finish OK.
Return exit code -1 if the program finish with error.

In addicion the program can return several exit codes for comunicate several error status, but retur 0 if sucesfull and -1 if terminate with error are the minimal.

It is very importan for control the aplication in batch archive or for call it from grafical interface.

Can you add this change.

I was with one old version.
Is not a bug in this version.
