Read and parse configuration files. Fixes #41. * supports nDPId / nDPIsrvd via command line parameter `-f` * nDPId: read general/tuning and libnDPI settings * support for settings risk domains libnDPI option via config file or via `-R` (Fixes #45, thanks to @UnveilTech) * added some documentation in the config file * adjusted Systemd and Debian packaging to make use of config files Signed-off-by: Toni Uhlig <matzeton@googlemail.com>
