Exporting modpacks as a .zip archive

Now you can click on the Export button to export a modpack as a .zip archive that you can send to your friends.

Now if a mod is available on Modrinth/CurseForge, but you didn't install it from Quadrant, you can identify the file, and bind it to the modpack manually.
