Allow grabbing a spline between two curve points to respect the
curve point types.

This means that the BCP of the splinepoints on either side of the
spline we are moving are going to be touched so that they effect the
other corresponding BCP for the corner point and will force the
adjacent splines to update themselves properly in response to your
mouse movement.

Allow grabbing a spline between two curve points to respect the curve point types.
New CV, View, Show, Control Points option to always be able to see BCP

As an added bonus, when this mode is on, you can also grab any BCP and
move it without having to select the splinepoint what owns the BCP you
want to move. That is: you can just grab any visible BCP and move it
as you like.
