[patch] Ensure that Basic Settings is always first admin panel

[ebray]

I have a plugin that provides an admin panel called "Advanced Settings" to the "General" category, so it ends up at the top of the admin navigation, and is the default admin panel.

But I certainly don't want "Advanced Settings" to be the default panel that users see when they click on the 'Admin' mainnav link.

So this ensures that the basic admin panel is always first.
