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

/**

* Make solid geometry for objects on layers.

|
|
* The operation is in the form (A - B) /\ C
|
|
* For almost all of the layers it translate something like:
|
|
* A (a via, a track, pad, polygon), B (a via hole, a THT hole, .. ),
|
|
* C the board (epoxy)
