These are used for replacing some hardcoded strings inside bot code, currently custom cvar for parachute detection is available, as well as custom c4 model names.
Added editorconfig, and fixed CRLF for files (was a mix between LF & CRLF).
Fixed use-after-free sanitizer error with chatlib.
Fixed configs files loaded with memory-loader does not process last line in config files.
Switch build to clang for linux.
Mingw binaries isn't working with vanilla hlds / listenserver. And i'm too lazy to debug them.
For consistency reason, linux switched clang, so we're only have clang for linux & osx and msvc for windows.
graph: allow saving / loading graph manually on dedicated server.
config: fix parsing for difficulty.cfg fixes#142
