Moved the init methods into a jquery ready function.
Made #events return this.
Added a new init method #exports to initialize exports.
Created an Application.Export class that checks current exports for status.
Added wizard styles to the stylesheets.
Made exports controllers #show and #index respond to json, xml and html.
Added an #export_filter helper.
Changed export view to show the export with a nice progress indicator.
Changed the button flow a little bit.
