“Scrape the Ape” plugin.

i ripped the widget code framework from Marcel Proulx http://www.district30.net and changed it a bit so it runs my Ape-Scrape. I’ll break my brains on the specifics of widget-codes later.

/*

do not expect to see this on wordpress.org ;) when i figure out how the widget code works i’ll make something proper.
