Bug fix for #1493 -

  - Changed shortcut of "Align Active Camera to View" to
    Ctrl+Alt+Numpad0 to make it Windows-friendly.

  - Old shortcut of Shift-Numpad0 still works (until we find some other
    use for it!)

Could use testing on KDE/Gnome, etc - incase we make X do somersaults or something equally daft! :P
