ENH: Handle -h, shorthelp and help when a Fatal Error happens.

Browse Source 
The user may need the help to solve any fatal error that appears while todo.sh isn't properly set up. As the help actions do not depend on any setting that the fatal errors check, we can still invoke them.

Factor out dieWithHelp() and use that for printing the fatal errors.
