Closes #1561
When a user enters something invalid in response to a prompt by the webinstall script, the script now displays a message such as:
Invalid input. Please try again or exit with Ctrl+C.
Additionally, for yes/no questions I have created the prompt_user_yes_no function, which simplifies the script a little bit since it gets rid of some duplicated code.
