Remove duplicate debug setting from deployment.ini_tmpl

deployement.ini_tmpl had debug = true at the top and then set debug =
false further down was overriding it. Set debug only once. Also since
this is deployment.ini_tmpl make the default debug = false and tell
people to set it true for development, not vice-versa.
