We can have only 1 console handler in the log.
Fixed a bug oin file_handler that makes it log
	as many times as load_config is called
console_loger can now log to the console.
When rotating files, if there are multiple files
	for mutiple handlers in the same dir
	delete only the files for the handler
	you are rotating.

A method erlog:start() that loads and start the application
