Way better performance

- load time cut in half (setup was being called twice)
- don't load webicons until it's required
- setup is now required (readme)

 ## Inspiration
 
 This behavior was inspired by vscode (sorry), that won't keep your tabs open until you hit save (or double-click the tab).
 
-To create the tabline I used [*mini.tabline*](https://github.com/echasnovski/mini.tabline/) as a starting point. It's a great plugin and the one I was using before. The label/tabs implementation on [`tabline.lua`](./lua/unclutter/tabline.lua) is an adaptation of *mini.tabline*'s code.
+To create the tabline I used [_mini.tabline_](https://github.com/echasnovski/mini.tabline/) as a starting point. It's a great plugin and the one I was using before. The label/tabs implementation on [`tabline.lua`](./lua/unclutter/tabline.lua) is an adaptation of _mini.tabline_'s code.
 
 Also this plugin was not only inspired by [harpoon](https://github.com/ThePrimeagen/harpoon) too, it's the main reason behind it. I was trying to hack harpoon to get this behavior, but didn't like the outcome. The plugin is great but I don't like their tabs implementation and other small stuff. It was there when I realized I could just code my own.
