Clogger 0.3.0 - configurable logging for Rack

Clogger is Rack middleware for logging HTTP requests. The log format
is customizable so you can specify exactly which fields to log.

Changes:

You may now force the :reentrant flag to +true+ or +false+ in
your Rack configuration file:

use Clogger,
:format => Clogger::Format::Combined,
:logger => ::File.open(“/path/to/log”, “ab”),
:reentrant => true

This is to be compatible with Rack servers that do not use use
events or Fibers for concurrency instead of threads. By
default, reentrancy is enabled if env[“rack.multithread”] is
true, but “rack.multithread” cannot indicative of a reentrancy
requirement in a web server.
