- converted sound and canvas texture serialization. - refactored file_zip, so that it can be used to load loose zip files and extract their compressed data directly. - added handling to FSerializer to generate and consume compressed Zip file entries. If all goes well this will allow saving savegames as Zips when the rework is done, which will make analyzing them a lot easier.
