Spline IK Bugfix:

Binding code had off-by-1 error, which meant that when "Even Divisions" was disabled the length of the wrong bone would get used.

This error was most noticeable when the lengths of the bones were quite different - for example, a chain with 3 bones of increasing length. Thanks to "Julius" on BlenderArtists for catching this. Cheers!

Also, simplified the binding code loop a bit to prevent this sort of error in future.
