HTTPS cert changes

o No longer use the self signed cert genetated by the mod_ssl package
o generate our own self signed cert
o add options so user can specify their own cert to use
o close port 80 if using ssl for horizon
o Adds a new resources member to the controller object, this contains
  a list of files to be copied to remote host
