[arch-dev-public] Package signoffs page

[Dan McGee]

Devs,

This seems like a good time to get the ball fully rolling on the
package signoffs page: https://www.archlinux.org/packages/signoffs/

I and a few others would like to make this the goto for signoffs-
fewer emails, easier to see at a glance what signoffs are pending,
etc. Given we have a large set of packages in [testing] right now for
some [core] signature rebuilds, this seems like an ideal time to get
some feedback so we can fully migrate to using this page.

So this is a call for (constructive) feedback on what more I need to
implement to make it useful to all of you. A list below is things
already on the todo list that definitely need to be done; if there are
other things that *need* to be done, please let me know. If there are
other things that would be nice, let me know too, but that might be
worth a feature request that can be worked on after we switch.

Must haves:
* A way to cancel a signoff
* Signoff "blacklist" or modification- basically say "this package
doesn't need signoffs, just remove it from display"
* A daily summary email saying "hey gang, here are today's pending signoffs"

Thanks!
