Changes Made

• added prompt_str(), prompt_int(), prompt_menu_options(), and prompt_date().
• I made a few changes compared to the issue description
  • All prompt_{x} functions return None when the user presses Ctrl+C during input. This is so that users can always cancel entering information.
    • This possibility will need to be considered when the functions are used, e.g by returning to a previous menu, exiting the application, etc.
  • Added prompt_date(), since we'll need it eventually anyway. It has optional min_date & max_date arguments, so we can dis-allow future dates, set a date minimum, etc.
  • Made char_limit optional - not all applications require a character limit.
  • Added numeric_limit to prompt_int, since it felt like a good idea and was needed by prompt_menu_item
  • Added examples for all of these functions in examples/prompting.py
  • Added a little color-printing class, ~just for fun~. Right now it has functions for printing warning & failure colors, as well as a generic version.
