These were renamed from "skip_"* to *. However, we only changed syntax
and didn't invert their semantic meaning. Fix this by negating the
semantics of those variables. Also, negate these in the configuration
file automatically when running `calcurse-upgrade`.

This isn't ready for distribution but allows users of the -git version
of calcurse to easily update their configuration files without having to
edit them manually.
Following things are still missing here:
* A command line parameter to specify a custom data directory.
* A backup file that is created automatically before upgrading.
* Debug output.
