Reorganizes the recipes in a more reasonable way.

The recipes are now structured into multipe subfolder and split into more
distinct files, so the names are more appropriate and are better at
hinting which items the actually contain.

It also extends the RecipeResourceCopier to now handle the folder
recursively and extract all subdirectories and their files.

"import=" is currently requiring a relative path to the root directory
of the recipes. This would require a larger rewrite/refactoring, thus it
is kept for now until a potentially later changer.

This reverts splitting the oredict entries into their own directory and
moves them back into the recipes folder, as it currently is causing a
couple of issues like not being able to resolve the aliases or is not
working indev. But to keep it seperate it is now its own recipe file.

Fixes #1791
Reverts #1635
