For some reason, escaped double quotes in wxString::Format cause issues
on Mac. We can replace them with single quotes in most places without

numberings that looked like decimals.
Instead, we use our natural string comparison function and remove the
references to this older function and its similar elements.

They don't define a KiCad string class, so the header file name was
somewhat misleading. But the fact that they didn't match definitely
made coding more difficult.
