Modified to use HHVM 3.2.0 and new build from the build scripts.
Fixed paths in the HHVM extension to work with the new HHVM binary zips.
Added config option to strip the front directory off of the path in the
zip.
Converted from old hdf format to new ini format.  One file, php.ini, has the PHP general configuration, the other server.ini has the HHVM server config.
Modified configuration to use unix sockets instead of localhost.
Removed rewrite of .env, no longer necessary.  Changed config to use .ini files.  Removed section to set the HHVM_LISTEN_TYPE as it's all now done via Unix socket.
Altered logging config so that HTTPD will log the remote ip address from x-forwarded-by and the peer. Altered remoteip config so that it'll work with other private ip ranges, like 172.16 and 192.168.
Added fix for NewRelic extension failure when using HHVM.
