The ability to re-order splines within Edit Spline.

[JezEmin]

I've googled how to do this and I cannot believe an operation this basic has never been addressed for such a mature piece of software.

An example would be for when using the CrossSection Modifier and one needs to move splines around and reorder them - their numbering then also needs to be changed too to reflect the reordering and new positions within the cross-section flow.

I've included this idea on my compilation of Spline procedural handling ideas. Pls support this and other great suggestions:
