Enu 0.1.97

Enu 0.1.97 is the first preview of Enu 0.2, which will be released in a few weeks. Significant new features since 0.1.2:

• A prototype based object system for instancing new units.
• Action Loops, simple state machines for managing unit behavior.
• API simplifications and improvements.
• A new somewhat forward compatible level format. Levels created in 0.1.97 will open in future versions, but may require edits to account for API and feature changes.
• Extensive internal changes. There's still some cruft, but I'm generally quite happy with the architecture.
• Expanded docs.
• Many old bugs fixed. Many new bugs created.
• Player can now stand on moving platforms, and will automatically climb 1 block elevations.
• Enu is a little bit smarter about merging builds together. This still needs work.
• Brown blocks! Added specifically for building potatoes.
• Native arm support under macos.
• Lots of other things that I'm not thinking of.

Still required for 0.2: https://github.com/dsrw/enu/tree/ce7d57109c8a24dd942ab9e74a29bed79ef9d475#todo-for-02

None of the builds are signed. The mac build will be signed from 0.2, and the windows build from 0.3.

Special thanks to @moigagoo for encouragement and support, and for sticking by the project after a full year without a release. Thank you!
