Support custom emotes

[deepbluev7]

Some clients support adding and sending custom emotes. Nheko does sometimes display them, but you may need to switch rooms once for it to load the emoji correctly.

Nheko should allow you to define your own emoji, send them and render them nicely.

The corresponding MSC is here: matrix-org/matrix-spec-proposals#2545

Looks like in the time since this issue was created, the rendering part was fixed (I'm using fluffychat to send). Now it's just that you can send stickers using Nheko, but not emoji.

Well, someone needs to twiddle them into the current input infrastructure and I so far have successfully avoided doing that ;-)

Ah, I didn't know about that

But animated emotes are not animated in Nheko, although the same image as sticker works. 😿

Animated images are hard enough to support, doing that in a text element will be a lot harder ;-)

I've added an ugly completer, that is accessible using ~ now. I want to unify the completers at some point and make it not insert raw html in the future, but I don't want to block access behind that :3
