Purchase new snowflake domain to fix "safe browsing" issue

*.bamsoftware.com is currently marked as "unsafe" by Google's "safe" browsing system, which breaks in-browser snowflake proxies. We don't know what caused this decision. It's probably a false positive because of an educational article but it may be snowflake itself. We are still waiting to hear back from Google.

We cannot transition the system to a torproject.org domain because if snowflake itself was the issue, we may end up getting torproject.org marked as unsafe too. Besides, our sysadmins may not like providing a domain for a system they don't control.

As a temporary solution, we could purchase another domain and transition to it. Examples are:

• snowflake.best
• snowflake.rocks
• snowflake.world
• snowflake.army
