CurseForge Download Replacer

This package will do two things: It will change the `Install` url from loading the Twitch client to simply downloading the zip archive of the modpack. It will also make two passes in an attempt to remove ads from modpack pages.

Note: The ad removal is done by removing `iframe` elements from the dom, so if curseforge ever starts using `iframe`s for anything besides ads, this will cause an issue.
