PowerShell v2 Function Set IISProcessModelLoadUserProfileBool

In a hurry, so not much time to do anything other than throw this out there. The real challenge for this one was finding the right way to find and set the global value. Using my favorite IIS link I tracked it down. For some reason the indexing starts at 1 instead of 0. Another mystery for another day.
