feat(screenshots): add swappy, add screenshot scripts and keybindings

* Add [swappy](https://github.com/jtheoof/swappy) for handling screenshots. It's a nice Flameshot-like tool that allows adding simple annotations (drawing circles, arrows, text, etc) to screenshots and can save to file or pass to the clipboard.
* Add keybindings for "snip", screenshot window, and screenshot current display.
* Add scripts for the screenshot window and screenshot current display functions.
* `packages-repository.txt` has also been alphabetically sorted to make it easier to work with.
