Make sure the user doesn't end up in a configuration file being totally
broken if the upgrade script fails unexpectedly. The backup file is
removed if the conversion completed successfully.

Instead of bailing out without any hint, show an error message if the
temporary file we use in calcurse-upgrade already exists.

Instead of creating the temporary file in a central location, place it
in the same directory as the configuration file. Pros:
* No need to rely on the "$TMPDIR" environment variable.
* Multiple users can upgrade their configuration files at the same time,
even if "$!" isn't set properly.
* One user can upgrade several configuration files (in different
directories or with different file names) at once.

Allow for specifying placeholders in shell scripts that are replaced
during build time. Predefine a "@PACKAGE_VERSION@" placeholder that is
replaced with the current version number. Also, rename all shell scripts
to ".sh.in".
