Greasy Fork镜像

So in v5.2.3.with.fixes.c, I had added fixes from PR #712. They were for fixing how Undiscord had become transparent and was impossible to see. Although Undiscord's GitHub still has v5.2.3, I learned that v5.2.4 is on Greasyfork. I compared it with my v5.2.3.with.fixes.c, and the two scripts are identical except that I have some very simple fixes for things like 401 errors. So I am updating the name of my script to v5.2.4.with.fixes.a. I will also attempt to create my very first Pull Request and see how that goes. Wish me luck.

There was an issue with the Undiscord window being transparent and impossible to see. I applied the following fixes: 90e7369, 0a144e7, and 672941b listed on https://github.com/victornpb/undiscord/pull/712. I noticed in 0a144e7 that there was a hashtag here '#undiscord .input' but for some reason it was written as 'undiscord .input' in the userscript. I added the hashtag because that is probably the correct syntax.
