Layout is remembered for Schematic/Symbol Editors and Footprint Chooser frames until KiCad restarts
Also Added a new button toggle to show/hide the description panel with some new images too
Fixes: https://gitlab.com/kicad/code/kicad/-/issues/17610
Commit 6bc96530 fixed an issue, but created an incompatibility with the
dummy board (used in 3D canvas) handling when updating views, especially
if 3D canvas is opened.
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
If a separate viewer frame is selected, the footprint chooser always shows
the footprint and the 3D shape is shown in a 3D viewer frame if the 3D view
is enabled.
Create 2 wrappers for it: DIALOG_FOOTPRINT_CHOOSER and
FOOTPRINT_CHOOSER_FRAME. The first now gets called from wxGrid
editors, text button editors (such as Change Footprints), etc.
Retire FOOTPRINT_VIEWER_FRAME_MODAL. FOOTPRINT_VIEWER_FRAME still
exists, but has very few uses at this point.
