Added an Inline Emoji Picker with keybinds

After a painful day of dealing with W3C's shitty fucking API's (uhh i mean great god bless u w3c i love you i love the web), I now introduce: Inline emoji picking

Is it :capybased:... is it :marseycapybara:, is it :capysoren:????? Oh great, time to open the emojo picker and see it- ACK

Gone are those days, just quickly type :capy and you'll get immediate results.

↓ (down) and ↑ (up) to navigate the emoji picker, ⏎ enter to select the emoji (or you can click it and use the mouse)

The design was heavily inspired my Pleroma's and Githubs. I hope you enjoy this power-dramanaut-friendly feature

If you use a wide-screen monitor, you'll notice the emoji picker is off... I fixed this bug, I am awaiting Aevann to merge this and make live lmao

I am working on auto-scrolling the emoji picker with arrow keys, it might roll out tomorrow
