Time based rolling file appender

[davide-prade]

Hi, I needed a time based rolling file appender. I attach the modified files to achieve this functionality.

I ask you to review it and to include in the next version on plog with the all related adjustments.

plog.zip

Here an example of initialization: plog::TimedRollingFileAppender<plog::TxtFormatter> fileAppender("test.log", "test.log.%Y%m%d-%H%M");
