Sugestion: keep all files only in the "addons/terrain_3d" directory

[Gnumaru]

Description

Currently, the demo directory is in the project root, as well as the icon.png. It would be nice if everything in the addon would be kept under the "addons/terrain_3d" so that users that quickly install things without paying much atention don't end up with files they don't know where they came from. Or, even if they pay attention, they won't have to mode the files by themselves after installing.

Specifically about icon.png, one could argue that it wouldn't be installed since it probably conflicts with the user's project icon, but not only nowadays the default icon is an svg (thus a different file path) but the user may configure any texture file with any path to be the project icon, so the terrain 3d's icon image would probably be downloaded and installed.

Please don't add unnecessary dependencies, like the demo, in addons/terrain_3d.

It's not a "dependency". In order to distribute your game, you would need to delete de demo directory anyway, regardless if it is in res://demo or res://addons/terrain_3d/demo. Even if it is inside the addon directory, the name itself makes it clear that it is a thing probably safe to be deleted. If an addon wants a demo directory to be outside it's addon directory in order to make it clear that it is not needed for the addon to work, then at least the directory name could be somethink like res://terrain3d_demo to make it clear and to prevent it from coliding with other "demo" directory other addons may create. If every addon decides do create a directory in the project root named with a word as common as "demo", we would potentially get a lot of name clashes. Perhaps the user wants to keep all the demos for all the addons he downloads, but if all of them have the same names, then that's a problem.

When I'm installing an addon, I don't pay too much attention to what's included in the addons/{{addon_name}}. I assume it's the code necessary for the addon to work. All the other directories are optional.

I don't want to accidentally end up with demo/... inside of my project files.
