Title: Rack::Request#trusted_proxy? regex is too strict.

Using Nginx + Phusion Passenger Standalone, the passed `REMOTE_ADDR` contains more then just `unix`. Often it contains `unix:` en sometimes `unix:'+ other characters`.

The regex to check `trusted_proxy?` is too strict for Passenger unix sockets.
