WLogger lacks file rerouting and file joint logging
WLogger currently only logs for the command line.
This should be changed so it will be possible to map the log into a file and deactivate the command line or even log both into the command line and to a file.
It should be even possible to log different logs into different files for example warnings and errors should be in errors.log but notices should be in notices.log.
The first part is very easy to implement, the second part of the feature is only a bit slightly harder.
