v3.0 beta reached

We're close, folks.

After a lot of spit-and-polish this week, I believe I'm at the point where I have "final" distributables of all Status Line executables, all Status Line Classics game file builds, and Status Line SPLIT functionality nailed down. As well, all itch.io webpage update work is done including the new page for SPLIT.

Final bits and bobs

• Update github
  • merge all final code
  • update READMEs
• End-to-end user testing
  • Run platform-specific standalone .exe
  • Run Classics Vol. 2 games on platforms
  • Split and play games on .exe
