Merge many XDarwin improvements:

- Fix launch of X clients by double clicking in the Finder when there is a
    space in the path (Torrey T. Lyons).
- Interpret scroll wheel mouse events correctly when shift is held down
    (Benjamin Burke).
- Add option to always use Mac command key equivalents (John Harper and
    Torrey T. Lyons).
- Add support for dynamic screen configuration changes in rootless mode
    (John Harper and Torrey T. Lyons).
- Add documentation on generic rootless layer (Torrey T. Lyons).
