Also removes a bunch of std::string stuff from the file handling in the
simulator. All our file handling, env variable expansion, project path,
etc. stuff is wxString based, and jumping through std::string in between
just makes it more complex and increases the potential bug surface.
Also fixes a bug where you'd get two error messages when a spice model
library wasn't found.
Also fixes a bug where you'd get a spice model library not found error
when the text field was empty.
Also fixes a bug where we'd try to absolutize a path starting with an
unresolved text or environment variable. If the path starts with a
variable it's probably absolute, and tacking on the project path in the
error message just obfuscates things.

- 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.
Implement parsing and loading Spice libraries into KiCad. This is done
without any involvement of Ngspice -- we create our own in-tree parser
using PEGTL -- because Ngspice doesn't offer any intermediate output we
could plug ourselves into. We don't parse everything -- just the library
content, so this won't be that much effort.
We implement some basic Spice code preview to give the user a hint what
Spice code eir model will correspond to.
