Qt Installer CLI validation is too strict when answering questions

Qt Installer does not accept short answers to questions that the user should expect to work based on experiences with other CLI software and is being too strict about capitalizing the first letter. This becomes even more of an annoyance with long words like Accept/Ignore.

Also there is no option selected by default when pressing Enter.
