[Sink] Simple file sink

[MarcSchaetz]

We need a Sink for writing to a file. This should be really simple because other sinks will take on the taks of writing in specific manners to files (daily, rotating, ...).

The file should be opened when the sink is created and closed when the sink is destroyed.

On logger.flush() the logged messages should be written to the sink. logger.log() should hold it in memory
