Addresses issue #101

So I'm not even sure if this was the proper way to address the Strict errors in WP, but it seems to have worked...except for the issues outlined [on WP support](http://wordpress.org/support/topic/attempting-to-fix-the-strict-errors-in-debug-mode?replies=3#post-5078437) and [StackExchange](http://wordpress.stackexchange.com/questions/128701/working-on-fixing-wp-front-end-editor-encountering-undefined-index). The widget wrapper throws an error when turned on, and still interferes with markup when it's turned off.
