Free42 state file switching, export, and import

[Thomas Okken]

I'm working on state file switching, export, and import in Free42. It's currently working in the Mac and Windows versions. I put test versions up here: https://thomasokken.com/free42/download/test/

These have a new platform-independent state file format.
The GTK (Linux), iOS, and Android versions will follow over the course of the next few weeks.

Comments welcome. Enjoy!

UPDATE (8/25): Release 2.5 is ready, and I removed the directory with the test builds from my web site, so the link shown above no longer works. The Android, Windows, MacOS, and Linux versions are available for download in the usual place. The Google Play Store and iOS App Store haven't approved 2.5 yet as I write this, but I expect it to show up there in the next day or two.
