Add a configuration file upgrade script

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.
