gtk-webkit-ruby 0.0.4

Gtk Webkit bindings for ruby. Partial coverage sufficient to embed a webview in a Ruby-GNOME2 application. Also initial/experimental support for allowing ruby code to be called by javascript & executing javascript from ruby. e.g require 'gtk2' require 'webkit' v = WebKit::WebView.new v.main_frame.setup_ruby puts v.main_frame.exec_js("ruby_eval('RUBY_DESCRIPTION')") puts v.main_frame.exec_js("document.root.innerHTML")
