Advancing Mailbox for Usermin

[iliajie]

Jamie, I'm about to start reworking Mailbox for Usermin to make our mail to be competitive with Gmail.

I need few things to add to the containers of mailbox/index.cgi when displaying mail.

1. Row Date, there is td that contains label, I need you to add attribute data-timestamp="linux-type-timestamp"
2. Row Size, there is also td that contains label tag, I need you to add attribute data-size="message-size-in-bytes-without-label-just-number"

There probably will be more. Let's start with it. I hope you will be able to do it as soon as possible, so I could merge those changes and start playing around.

Sure, that all sounds good to me!
