This introduces a logger mechanism and a new data/log directory. This is
a first proof of concept. It's built on top of the new global error

to drop-in other psr3 loggers?
* how to configure which facilities shall be logged?
* should we implement a log deletion feature?
* is the log format sensible?
* should we implement a log viewer admin plugin?
* should logging trigger events (it should maybe replace the
