Subject: haproxy-devel, improvements (but 'breaks' parts current config)
 -moved the 'backend' config fields to page where they make more sense without
 "magic merging" of frontend settings.. -certificate can now be chosen from
 certificate manager certificates

to find any 'config problems' run "haproxy -c -V -f /var/etc/haproxy.cfg" on a console/ssh session
