This commit adds a simplified logging system, with two primary methods:
- `Logger#log(String) :: void` (for normal logging)
- `Logger#debug(String) :: void` (for debug logging)
This helps dramatically simplify logging infrastructure, as well as
enabling simpler toggling of log modes.
The configuration values for the Logger have also been updated:
- `logger :: Function` - function to log output to (both normal + debug)
- `silent :: Boolean` - whether to log default normal messages or not (`--silent` flag)
- `debug :: Boolean` - whether or not to log debug output (`--debug` flag)
Additionally, the following CLI flags are supported re: logging:
- `--silent` disables normal logging (will override all other settings)
- `--debug` enables debug logging
Deprecation notices have been added for old log methods, with first-run
messages to this effect.
This change should have negligible impact on end-users, with minor
inconvenience for library developers, as they need to switch their
logging function calls over.
Logging configuration is still possible via both
`Cylon.Config.update(Object)`, and directly calling
`Cylon.Logger.setup(Object)`.
