Is there an option to set log level?

[Willyarma]

Not important, but I was wondering if there was an option to set the log level?
Thanks for all your hard work on this amazing software.

See #159.

Some examples: https://docs.oracle.com/cd/E29578_01/webhelp/cas_webcrawler/src/cwcg_config_log4j_file.html

(I should probably write something about logging in the README)

Could this be added as option (to config file) so there would be no need to build the project from source after every update?
