Beta version 0.4.1

This is a minor fix to the fourth beta release of the XCI adventure game engine for the Commander X16 retrocomputer and cross-platform software development kit (SDK).

Fix only affects Windows SDK. No changes for X16 engine and Linux SDK is rebuilt, but functionally identical to v0.4b.

The following binaries come with this release:

XCI.PRG - Game engine for Commander X16 (requires build R37 of X16 emulator/ROM)
xci_sdk_linux_amd64.tar.gz - XCI SDK for 64-bit Linux running on x86 system (xci.exe, archived)
xci_sdk_windows_mingw64.zip - XCI SDK for 64-bit Windows (xci.exe, archived)

Running the SDK on other platforms requires compiling from source using GNU make and gcc. See README.md for build instructions.

Issues resolved:
#4 - Hex files now being written as proper binary files across platforms

Known issue:
#5 - Exit does not go to BASIC prompt
