[ANN] clogger 1.0.0 - configurable request logging for Rack

[Eric Wong]

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

* http://clogger.rubyforge.org/
* (e-mail address removed)
* git://bogomips.org/clogger.git

Changes:

* $time_iso8601 added for nginx compatibility
* $time_local (without strftime-options) is now locale-independent

There's also a minor usability tweak that allows Symbols to be
specified as the :format argument, so config.ru can be shortened:

before (continues to work with 1.0.0):

use Clogger, :format => Clogger::Format::Rack_1_0

after:

use Clogger, :format => :Rack_1_0
