Logging misses some information leaked to stdin

[Teebor-Choka]

While analyzing logs on a development setup I noticed that a lot if information is passed to stdin using the print() function. Some of the more crucial information (such as input check) did not even make it into logger facilities.

A preferable solution would be to use a dedicated (configurable) logger for each such output instead of the print() functions (those should be removed). The default destination for the logging could be set as stdin, which is by default captured on external systems.

Using logger allows to select the logging message granularity and allows easier debugging.

Some of the print() invocations that can be found by a fast grep (notice the Critical problem during execution {e} which never makes it to the log):
