TFS Polling, Screen Flicker, User Mappings

Sorry for the state of some of these commits. I am still getting the hang of Git and GitHub. I apologise if there are CR/LF issues. I have tried to avoid them by following the help on GitHub but they may still be present. Let me know if there is something I can do to fix them.
