Add an a flag to the Linux server installer to automatically accept the defaults

This would clean up some of the automated installs of the server instead of needing another program to assist.

Have the flag be something like --accept-defaults. That way it can run without any user interaction.

Piping the script to 'yes' doesn't work well, as the questions are not always y/n based. Entering the path requires an Enter command, as does the Servicename.
