CraftOS-PC v2.2.5

This is a relatively small release, but it fixes a few crashes and adds some new command-line functionality. This version is mainly released to support daelvn's COSRun tool for running projects in CraftOS-PC directly from the terminal; go check it out!

• Added --directory argument to specify custom data directory
• Added --id argument to specify launch computer, overriding initialComputer config option
• Rewrote --script argument to no longer shadow real startup.lua (#83)
• Added header option to http.websocket to match CC: Tweaked behavior (#82)
• Fixed crash when writing below screen
• Fixed crash when closing WebSocket
• Fixed terminal background not being affected by palette changes
