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.

Also includes fixes for instance data and resolving of textvar
references.
Also includes virtual d'tors for IBIS parser to get rid of all the
compile warnings on CLang.

Load the library from the path if enter is pressed or focus is lost if
the library exists. If a library under the same path as previously is
to be loaded this way, don't do anything.
