Support for URLs with spaces in them.

So, if I share a URL, like this - https://imgur.com/t/lesbian horse shrieking/62zRAfI - it is perfectly valid in the web browser but Discord cuts it off after 'lesbian' and anyone clicking on it will try to load https://imgur.com/t/lesbian and not the entire URL. BTW, don't ask, I have * no * idea why Imgur used that URL. It's a G rated MLP clip. I can't find the other example I had earlier, it was something like imgur.com/star wars ... something. >.< And it cut off at 'star' due to the space.
