Add option to automate test installation

[paultpearson]

Would it be possible to add a question at the beginning of the installation that says "accept all of the default values?" for the purposes of creating a private WeBWorK test installation (not a production installation)? This option would mean that the user is prompted far fewer times, thereby speeding up the installation process and minimizing errors caused by entering an incorrect value at a prompt.

Hi Paul - I have a branch that is implementing exactly that. I'll be merging it in soon.
