Autodownload CentOS, Autofind GuestAdditions on Mac, Test IP and Detect Local IP on Mac

I made a number of improvements but left it backwards compatible with the way the script functioned before.

Overall what do you think of the improvements? Do you run this on a mac or other environment?

Yeah, I'm on a Mac most of the time but I would like to try and keep as cross-platform as possible. Overall, automating the process along is definitely a win. I have kinda have got used to a workflow so it's nice to see some perspective like this and see where the pain points are :) . I'll splice and dice the bits I like and pop them in ASAP.

Something I've been thinking I should do is have some sort of "contributor agreement". Would you be happy if your work here was put in the public domain?

[smorin]

As for crossplatform, I did checks so that should work fine for most people.

I am using this for my production so would like to keep in sync. I rather not have a fork. I would be happy to be a contributor or just submit pull requests like this.

I am also curious let me know which parts you like and don't like.

Would be happy to change differently if you want, because I want my copy as a downstream to maintain this functionality.
