Minima got two bug fixes and a new Raspberry Pi version

Minima got fixes for two minor bugs that have been lurking unreported for a long time.

The first is that it was possible to find a certain magic item and search again in the same location and get a second (and third and fourth etc.) message that it was found, even though you were really only finding it once. This has been fixed.

The second is that when using the look command in dungeons in the uninteresting case of there being nothing there, it'd erroneously report there being a "wall" instead of a "passage" like it was supposed to. This has also been fixed.

As part of this release Minima has been updated to use the latest & greatest PICO-8 version, and consequently we've got a Raspberry Pi build now! If you've got one of those little handheld Pi gaming systems, it now ought to be pretty straightforward to get Minima running on it.
