pbc-0.5.9 released

Michael Adjedj fixed a bug which caused element_pairing() to fail because of an uninitialized pointer.

Also I supported a feature request from Zi Lin, who wanted to raise an element in a finite group to an enormous power. The library now detects this and reduces the power modulo the order of the group before proceeding with the main loop.
