CEN64

`19:20 tag a release` k. On a more serious note: This tag marks the end of me maintaining the current interpreter-based version of CEN64, v0.3. The current version is "runnable" and doesn't seem to have any show-stopping bugs filed against it. At the same time, I'm not pleased with the performance of this software and genuinely do not believe that incremental fixes will yield something that is acceptable to me. Looking forward, bigger and better things are coming. A lot of things have been learned from this release, and a lot of progress has been made. Thank you to everyone out there who has contributed both directly and indirectly to this software. For anyone who has contributed to this software: I want to assure you that your contributions are being folded into the new release (which is no longer based on an interpreter design) and that it will, of course, remain open source software licensed under the 3-clause BSD license, as always. Any further contributions to this release (v0.3) will be accepted and merged into a patch-level release on an as-needed basis.
