You should now use Tools.RandomId(), this method is still here for legacy reasons.

Implementation from http://stackoverflow.com/questions/105034/how-to-create-a-guid-uuid-in-javascript/2117523#answer-2117523

Be aware Math.random() could cause collisions, but:

"All but 6 of the 128 bits of the ID are randomly generated, which means that for any two ids, there's a 1 in 2^^122 (or 5.3x10^^36) chance they'll collide"
