Added Boxer 4.1 Beta

I have updated the Boxer versions on boxer.thec0de.com to include both 2.0 and 4.1 Beta.

The reason for this update was to have a version that supports Apple Silicon CPUs. If you want to read more about it you can check the github repo here:

There is a known bug worth mentioning:

Quitting Boxer after running DOS causes Boxer to crash.

I take no credit for this build – It is credited to MaddTheSane.
