clogger 1.0.0 - \o/

clogger 1.0.0 - \o/

* $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
