Update rename script to include option to specify domain

[vcantu]

This just adds a third prompt to the rename.js script to specify a company domain.

This is incase a company has a domain name other than [company name].com

I would also like to see an enhancement to the script that allows it it be rerun. While not a big deal, it can be a pain the ass if you make a mistake and you have to reset your clone, or later on if you want to rename it would be awesome to support that.

Unfortunately this went stale and has a conflict now, before anyone looked at it :-(, if you are still interested and could fix the conflict I'll merge it in
