* Made fail2ban settings more consistent across OSes, disabled HTTP ratelimit permaban on Debian as auto-refresh behaviour in FusionPBX can trigger it.
* Increase nginx-404 ban back to 1 hour
* adding devuan
* add devaun desc to README
make update and upgrade more noisy
correct path for devuan in pre-install
* some untested code for the source install - source installation is broken in Debian installation script and I have not debugged the problem. Focusing on the packaged version first.
