Non-Release 41.1.0

This Non-Release updates Box16 to support x16emu's r41 ROM release. Technically there wasn't a whole lot to update from r40 to r41, and I'd even forgotten to update the program's versioning info. This non-release, however, includes a variety of fixes, improvements, and updates that don't break the behavior of the r41 ROM.

As always: Bug reports welcome. PRs welcome.

Pre-built Windows zip files are available for Box16. You still need to build or acquire your own rom.bin from the official X16 emulator's r41 release, just place it in the same directory as Box16.exe.
