allow specification of domain words through cli arguments

This commit allows the specification of a word or multiple words to be domain-ified and checked.

For example, if I called

    $turboname peanutbutter andjelly

I would get back
```

 ________  _____  ___  ____  _  _____   __  _______
/_  __/ / / / _ \/ _ )/ __ \/ |/ / _ | /  |/  / __/
 / / / /_/ / , _/ _  / /_/ /    / __ |/ /|_/ / _/  
/_/  \____/_/|_/____/\____/_/|_/_/ |_/_/  /_/___/  
    finding a domain name for you since 1825
peanutbutter.com         is not available
peanutbutt.er            is not available
andjelly.com             is not available
andjel.ly                IS available
```

If no arguments are present, it continues as normal.

Note: I removed the 15 character limit check for "Specific Word Mode" because the user is specifying the word in the first place.
