[Userscript] Show banned games when creating a new GA

A while ago I hacked together another Userscript to show me whether a game is banned when I try to create a giveaway.
Nearly the same time, cg announced that he plans to allow GAs free games someday soon.
So I decided to not release the script, since it seemed pointless. Since then, a few weeks passed and it turned out to be really helpful to me, while there were no news towards allowing free games, so I changed my mind about that. Long story short, here is the script.

Some notes upfront: I made this mostly for myself and release it because I think it is pretty useful. Nevertheless, it has some quirks:

• The script fetches the list from shauntmw's great Can we have a list of games that cannot be created as giveaway? thread. That means, it is not complete and also not always up to date. It should be seen as a little help when creating GAs, but you should not depend on it.
• I did not implement any kind of pagination. So when you start typing or just enter few letters, the list will be huge.
• The list is refreshed on every page load on /giveaways/new. If you finish typing your game title before the list is updated, the results from a cached list are displayed. Meaning, that it may be that the new entries aren't in the list yet. In this case, try deleting and retyping the games name - as soon the list is updated, the new data is used.
• I will provide basic support like fixing bugs which makes the script crash, but I won't add any fancy new features, especially if it looks like much work. As soon as cg releases the free games for us, this script will be useless - at least for detecting free games. I won't sacrifice my free time for something that may become obsolete tomorrow.

TL;DR

• Shows banned games on top of the the list when creating new GAs

Install

You'll need a scriptmanager like Tampermonkey in Chrome or Greasemonkey in Firefox to install this script
