/* Userscript to add a QRWP code display option to toolbar
/*
/* Generates a QRWP code image using the current Wikipedia page URL.
/* Demo version so use at your own risk!
/*
/* Initial failure to display in the Toolbox may be due to:
/* . needing to purge the page cache
/* . or you may be on a page without "What links here"
/* . the order of javascript changes might stop the link being added. If you 
/*   have 'addOnloadHook', it may need to run there rather than earlier.
