No more scenery in the Resources/Earth nav data folder.

Back in X-Plane 7 the default scenery location was the "Earth nav data" folder of the Resources folder. Custom scenery went into packages in the "Custom Scenery" folder, just like now.

In X-Plane 8 we introduced the concept of a "default scenery" folder in the resources folder. The default scenery folder acts exactly like the custom scenery folder, in that it holds scenery "packages", but it has two special properties:

1. Packages in this folder have lower priority than any custom scenery package.
2. It is in the resources folder and is therefore the turf of Laminar Research and our updater -- the Custom Scenery folder is for third parties.

Okay that's not really a special property, more of a convention. But the main idea here was to remove special cases from the scenery system...in X-Plane 8, all scenery comes in packages, no matter what it is and who ships it.

Scenery comes in packages, period. Repeat it like a mantra.

The original X-Plane 8.0 still installed legacy ENV files into the Resources/Earth nav data folder (but installed DSFs into a package). X-Plane 8.20 (when we shipped full DSF scenery) installs everything into packages, as will all future versions of X-Plane.

X-Plane 8 still looks in "Resources/Earth nav data" as a last resort. But this is going away! Future versions of X-Plane will only look for real scenery packages in the "Custom Scenery" and "Default Scenery" folders.

What does this mean to you? Almost certainly nothing...but...

• If you are an author and your scenery needs to be installed into the resources/Earth nav data folder, fer cryin' out loud, please put your scenery into a custom scenery package. It takes about 5 seconds and will make life easier for you and your users.
• If you are a user and you have been moving files into the the resources/Earth nav data folder, please don't do this! Learn how scenery packages work and put whatever you've been moving into a custom scenery pack. You'll find things much easier to deal with.
