Require a [MENU] press to change a curve type on editor

[GoogleCodeExporter]

It's very easy to destroy a curve when trying to edit it because curve type is 
already selected and a press of LEFT or RIGHT directly change it.
I'd prefer having to press MENU before it can be changed.

To see actual behaviour:

- Create 5Pt curve and edit the 2nd point
- Exit the curve edition screen
- Edit again your curve
- Press LEFT when on the screen
- You've lost the position of your 2nd point, and it can't be undone if 
selecting again a 5Pt type curve.

I messed up a few time at the field with that this morning ;)
