Custom.cfg (#213)

Added custom configs.

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.
