Biweekly Update #2 - autosaves and plugins

Hope everyone is keeping safe and healthy!
This update includes the autosave system, so you no longer have to start a new game every time you launch the game. Cryptopunk uses a roguelike save system, so you cannot revert to earlier saves.

The big news in terms of gameplay is the addition of plugins. These are upgrades that enhance the abilities of your hacking programs, but increase their size. Plugins can be bought in the shop like programs, and every program has at least one plugin slot.
