Changing the pluscal translator

The pluscal translator can be thought as the pluscal "compiler" which takes as input pluscal code and produces tla+ in output.

For this reason, the pluscal translator is versioned. Any change to the pluscal traslator that could result in a different output, will required a verison bump.
