Update easy-arch.sh
mainly changed functions with user input (except password-related ones since i don't know how to apply it to those) to use a different method for repeating questions to fix the issue of commands repeating if incorrect answers were given before a correct one (this is the reason why the password selection functions use while loops for incorrect answers instead of re-running the function). the method used is described in this StackExchange answer: https://unix.stackexchange.com/a/268769
