Rename project to Commonwealth Online

Replace occurrences of "Fallout 4 Together" with "Commonwealth Online" across docs and testing guidance. Add Interface assets and tooling: MainMenu/Pipboy SWFs, translation/fonts, exported scripts (Interface/exported/scripts/MainMenu.as) and a PATCH_MainMenu_Multiplayer.md describing how to add a Multiplayer menu entry that calls root.f4se.plugins.commonwealthOnline.openManager(). Also add build/run batch scripts and apply assorted updates to README, plugin, server and protocol documentation/source to align with the rename and UI changes.
