Can't update TTL of domain with multiple A records

[jsoref]

I have:

mail.example.com 127.1.0.1 0 60
mail.example.com 127.1.0.2 0 60
mail.example.com 127.1.0.3 0 60
mail.example.com 127.1.0.4 0 60

I want to change that to:

mail.example.com 127.1.0.1 0 600
mail.example.com 127.1.0.2 0 600
mail.example.com 127.1.0.3 0 600
mail.example.com 127.1.0.4 0 600

I tried listing the example.com domain, going to the page w/ mail.... and changing each ttl from 60 to 600.

I get an error saying that each TTL must be the same, one error per row I'm changing.

As a result of the merge of #334, we have another issue :)

Sigh. 2 steps forward 1 step back?

I'm on vacation. I guess to deal with this, we'd have to check to see if all proposed items are consistent and cover all names.

I decided to delay fixing this issue until the next release, since we need to rethink validations. Now, the main focus is on fixing the current DNSSEC implementation.
