Old common files used by kicad - Transitional Package

 All the typical used an needed libraries like the schematic symbols, footprints
 and templates are now provided by the metapackage 'kicad-libraries' which will
 be pulled from this transitional package.
 .
 3D models are moved over to package kicad-packages3d which is currently only
 suggested due the installation size.
 .
 This is a transitional package. It can be safely removed.
