Keyboard interrupt not handled when waiting for user input

[jose1711]

To reproduce:

• start calcure
• hit a to add event (but note that d or r works too)
• press ctrl+c

Receive KeyboardInterrupt message:

_curses.error: no input

Indeed, I was aware of this possibility for a while. I think I should write an error handling decorator in dialogues.py module.

Thanks, I believe user should be given an option to use Ctrl+c as a way of terminating the current action. Example:

• user hits x
• status line: Delete event number: (^c to abort)
• user realizes error, hits ctrl+c
• nothing happens, status line updates to Aborted
