Subject: Finalized magic function _prep_function(). Gets returned when a
 profile is imported through archinstall.select_profile() user-interaction
 helper function. Asks for additional user-input right away rather than half
 way into the installation. This makes sure user input is taken care of before
 starting the installation. Although it complicates the code layout a tiny
 bit. Profiles need a __name__ and a _prep_function combo in order to be
 safely executed by select_profile(). select_profile() will not attempt to run
 or execute the code in any way unless those to conditions are met. In theory
 :)
