Unfortunately, Windows headers define a lot of macros for common words,
so we had to rename some enums to not collide.
We also fix some of the many bugs related to the new simulation
architecture and the Spice Model Editor dialog.
- Tab-switching,
- Automatic expansion of categories on tab-switch,
- Various minor simulation improvements,
- Various new simulation-related bugfixes.
Rewrite the spice exporter to work with the new simulation model
architecture and data model, with many bugfixes related to the latter
two along the way.
