Fixed ResourceAVMedia not being serialisable and also resources not being destroyed when a project is closed (causing things like file handles to stay open until closing the editor), added online/offline indicator in resource manager (red outline + red header), replaced standard message box usage with custom one (for the dark theme :D), added frame progress text block to export dialog
