Quit prompt

Since on QWERTY keyboards 'Q' and 'W' are next to each other and most of text editors have this feature, I thought it would have been nice to add a prompt to ask the user if he wants to save changes (or abort) on quit command.

I've implemented a variable unsaved_changes which becomes 1 after making any change. If the edit command ('e') is performed, the variable is set to 1, only if the line content has actually changed.

The variable is reset to 0 after performing save command ('w')

On quit the user is prompted, in case the variable has value 1, to save changes before exit or not. The user can also cancel the quit action.

I hope this change looks useful to you.
