Revert "ChildOf Constraint: Hide the Loc/Rot/Scale toggles"

This reverts commit 4fd78bb06faa31f265af6a5f247cf4255b5ac479.

After further testing, it turns out that these options are less-broken than
I remember them being (and have been hearing about). Specifically, as long
as you disable all 3-axes of a transform component (i.e. all location, all
rotation, all scale) you're not likely to have problems, whereas if you only
disabled one axis (i.e. y-rotation), you may have problems in some cases.

So, restoring these to the UI.
