Add alacritty

It turns out that I don't actually *need* image output in the terminal
(besides being cool). With that aside, I can safely use alacritty
knowing that it's written in Rust and is apparently the fastest terminal
emulator in existence.

+# alacritty
+
+[alacritty][alacritty] is a new terminal emulator written in Rust.
+
+## Use Cases
+
+alacritty can be used to:
+
+- Have a terminal emulator that just works.
+- Have a terminal emulator with modern features like live reload, and without all the extras like window management.
+- Master [tmux](/tmux) since you won't be relying on window management of your terminal emulator.
+
+You should not use alacritty if:
+
+- You have a desire to output images in your terminal (use [kitty](/kitty) instead, since [libsixel][lixsixel] support is WIP)
+- You have a need to use Japanese input in your terminal ([an issue][ime-support] for over 3 years in alacritty). [kitty](/kitty) supports this, however.
