Footprints can now have a custom stackup. This means that they specify
an exact number of copper layers and the layers map 1:1 to board layers.
If the board doesn't contain that layer, the element just doesn't
show. We could make this a DRC check later on.
If there is no stackup, the behavior is the current default: a rule area
the In1 layer "expands" to all Inner layers.

ADDED: description of jumper groups for PCB Footprint
Properties dialog.
Also untangles the internal storage of the DRC exclusion
flags from the fabrication attributes.
Also removes allow-missing-courtyards from PCB footprint
properties because you can't edit the courtyards there
so it makes no sense.
(Which means the library parity checker also doesn't
need to check it as it will always match the library.)
1) Don't set user layer count right after we've
cleared the enabled user layers. (It will
always be 0 by then.)
2) Allow un-enabled layers in some layer
selectors. (Currently this is just the private
layers selector.
3) Reset the appearance panel layers each time a
footprint is loaded. Also, auto-enable any user
layers that the footprint already has.
4) Footprint editor layer visibility is stored in
the view, not in the boars (as is usual).

Each editor needs the embedded files tab in the
schematic/pcb/symbol/footprint settings. But the footprint may add an
embedded file from the 3d models tab and symbols/footprints may add
embedded files from the grid. This should be immediately visible in the
embedded files tab. Additionally, removing the reference to an embedded
file in the grid or 3d models now removes the embedded file as well.

We still conflate the fieldID, the position in the
array of fields, and whether or not that means the
field is mandatory. But this attempts to clean up
*some* of that, without introducing too much risk.
Recommendation is to avoid using the year nomenclature as this
information is already encoded in the git repo. Avoids needing to
repeatly update.
Also updates AUTHORS.txt from current repo with contributor names
Schematics, symbols, boards and footprints all get the ability to store
files inside their file structures. File lookups now have a
kicad-embed:// URI to allow various parts of KiCad to refer to files
stored in this manner.
kicad-embed://datasheet.pdf references the file named "datasheet.pdf"
embedded in the document. Embeds are allowed in schematics, boards,
symbols and footprints. Currently supported embeddings are Datasheets,
3D Models and drawingsheets
