* Patch from Melanie. Mantis 0001037: Add various internal plumbing to the example economy module, implements llSetPayPrice(), money() and llGiveMoney() in scripts. Thanks Melanie!

* Moves module loading before the script engine so the script engine can pick up events from modules registering interfaces with scene.
