- Tweaked the build to copy `settings_example.json` to `settings.json` if
it doesn't exist.
- Updated the readme to reflect changes with modules and the Makefile.
Functions added:
- LogErrorf()
- LogErrorln()
- LogChatf()
- LogChatln()
- LogInfof()
- LogInfoln()
- LogDebugf()
- LogDebugln()
- LogDevf()
- LogDevln()
New settings configure the logging: LogLevel and LogFile. LogLevel can
be set to one of: error, chat, info, or debug and will default to
error. LogFile is an optional file to write to. Providing a file will
not prevent output in the console.
LogDevf() and LogDevln() only compile when the "dev" flag passed to
build. This will cause Travis-CI to fail the build if it finds any
calls to either function.
