Add Domain Aliases In Bulk

As a systems administrator, I'd like to be able to add domain aliases in bulk via CSV/textarea, so I can quickly create multiple aliases in a short amount of time.

I needed to add thousands of domain aliases to one of my sites, so I had to code my own php solution. Running this took forever and I had tons of issues along the way.

I suggest adding both of these:

1. Textbox for up to 500-1000 domains to process

2. Upload a CSV

This would allow everyone to easily add many domain aliases and would likely cut the creation time down dramatically.
