Add recent & favourite fonts

Not every font is well optimized for pixel art, and so people either download custom ones, or make them themselves. Either way, they have to either scroll through their fonts, or remember the font name to be able to quickly search them up. Adding a simple “Recently used” and “Favourite font” tabs would speed up that process and allow users to group pixel art optimized fonts in a single place. This is currently doable if the folder from which we’re looking for the font files is separate than the system fonts, but in that case you’d have to download the fonts and keep them separate, which is annoying. Simply installing a font, opening Asesprite, and favouriting it, would be much quicker and intuitive imho.
