Iowa now works with WEBrick!

In this release, the process for using WEBrick has been streamlined over the
0.9 release.  All one needs to do now is create a startup file in the same style
as if one were using Iowa with Apache or another seperate web server, except
that one require's 'iowa_webrick' instead of 'iowa'.

i.e.

webrick_demo.rb
-----
require 'iowa_webrick'

class MyApplication < Iowa::Application

	attr_accessor :mapfile

	def initialize(*args)
		@@cachedSessions = 10
		@mapfile = 'mapfile.cnf'
		super
	end
end

Iowa.startDaemon('webrick_demo.cnf')
Iowa.run
-----

By default, iowa_webrick assumes that the docroot is, relative to the iowa
directory, at '../htdocs', that the cgi-bin root is at '../cgi-bin' and is
accessed as '/cgi-bin', and that it is running against port 2000.  One can add
a webrick section to the cnf file in order to override the default webrick
configuration.  That section in the .cnf file would look something like
this:

webrick:
  docroot: ../doc
  cgiprefix: /cgi
  cgiroot: ../cgi
  port: 80
  

There is an example in examples/webrick/iowa that should help you get started.
