Script Summary: This adds an option to StumbleUpon forum threads allowing you to double-post or provide your browser info.

Thanks to Josh1billion for the idea and for providing a working example.
Unfortunately, his userscript was incompatible with Preview SU Posts. He was kind enough to allow me to rework the idea, and this is the result.
Note: This double-posting feature has been intentionally excluded from userscripts in the past, as there is a risk of abuse. Please do not use the feature in forums where it is not welcome, and do not use it to spam. Thanks.
