Title: No longer assuming users are homeless

With this configuration enabled, users are assumed to be homeless. That forces Assetic to use /tmp as $HOME, which in turn bypasses your entire Ruby setup. Including the very popular Ruby Version Manager (RVM).

My commit changes the configuration to what I feel is a much more sensible default.
