Split the implementation logic into separate files/modules

The main implementation file BloodBash is huge. Makes it hard to grok. Better separate concerns into separate modules.

It's intentional to keep it as a single file to make it easy to pull down and execute.

One thing I am considering is compiling it in dotnet core and a couple other languages that can produce a single binary. The goal is to keep it easy to execute and move. Not install

Easily remedied with a script for moving. I prefer clean code to portability. If compilation as a route, I vote for Go or Zig.
