The quite ugly hack with std_err_override seems to have been made for python < 2.7. Since all major distros
have al least python 2.7 installed we can stop using the std_err_override hack.
This removes it from pypo, media-monitor still uses the module and we can completely delete it when we have
remove media-monitor after having maybe backported the watched folders feature to analyzer.
* Removed Support Settings nav link
* SAAS-801: pypo log configuration files are overkill and must be removed
* CC-6043: CTRL-C doesn't work in pypo / airtime-playout
