Add Linux compatibility for LoginServer

- Updated main.cpp with platform-specific code for Windows/Linux
- Modified stdafx.h to include Linux headers and definitions
- Updated signal_handler.cpp for cross-platform signal handling
- Added Linux-compatible types and macros
- Created CMakeLists.txt for Linux build system
- Added build.sh script for automated building
- Added loginserver.sh script for server management
- Created comprehensive README_LINUX.md with deployment instructions
- All changes maintain Windows compatibility using preprocessor directives
