Subject: src/config.c: Drop support for legacy color schemes

We used different naming schemes in versions prior to 1.8. Given that
calcurse 1.8 has been released more than 4.5 years ago, remove the
legacy code that still handles these. Users upgrading from <1.8 to 3.0.0
might need to convert the appropriate config file variable manually.
