Data save and removal of the progress bar

The function io_save_cal() saves apts, todos, configuration data and key
bindings. The configuration and key files do not belong with the two data
files, but the progress bar function assumes that all four files are saved in
a fixed sequence. Since it is used nowhere else and contains unused parts,
the function has been removed.

A return code for file access error is introduced, and the EXIT macro moved to
the command level in calcurse.c.

Save of configuration and key data were already moved to the configuration menu
in commit 0124618, A save refinement: no action if everything is unchanged.
