Resume-from commands not calculating number of pings

[VKotwicki]

When using resume-from-last/resume-from-file, it will check all users that have already sent a response. However, it doesn't check how many times the user has been pinged.

Duodo needs to check how many times a user has been pinged, and if it's less then the required pings, keep the user if they have not sent a fraud or accept response.

It'll also need to check how many more times the user needs to be pinged. This'll require a change to the push loop.
