Man, dealing with the launcher is hard. But I've got it about as good as I can:

* when installing 3.5.1 over 3.5.0, user has the option to update/not update the launcher (no option to uninstall at that time)
* after installing 3.5.1, launcher can be added via Modify, but not removed - the checkbox is now disabled with this change
* with 3.5.1, the launcher has its own entry in Programs and Features (from a different bug)
* uninstalling 3.5.1 does not automatically uninstall the launcher

This patch updates the help text in the installer to better explain what's going on, and now gets the "requires admin" icon correct.

Larry - this change is fully contained to the installer and (along with the original part of the issue above) should avoid a lot of confusion once we release. Can I have it in 3.5.1? I'm happy to rebase and push directly to your repo.
