* Changed the Curve Modifier to have it's own X/Y/Z axis deform direction
settings, rather than using the object's TrackX/Y/Z/etc buttons.

This is good for two reasons: a) having the settings over in the object buttons
before was terribly unintuitive and hidden, now it's more visible how to
control the deformation, and b) now if you have more than one curve modifier,
they can have their own settings, instead of being forced to use the object
level data.
