Pixilart Gallery Exporter

Creates and saves a .zip file of the user's gallery on pixilart.com. The extension will only work once the user opens a logged-in pixilart tab after installing. The extension allows pixilart users with large galleries to quickly save a local copy of their work and avoid manually downloading each drawing, rather than exclusively relying on external servers to store their art. The extension was made while referencing code from the pixilart themer and mass post editor by Quinn; a few lines of code in this extension are pulled directly from hers.
