Add RCG column in WU History section

[muziqaz]

I swear this was discussed somewhere, but cannot find it.
So we have a situation with a new project where we are seeing repeat WUs coming back to us over and over, even though they were completed successfully before, even by the same machine. So we know that it might be a project set up, which is wrong, but we are still not sure what exactly is broken. Having a RCG column in WU history would allow us to quickly filter by project and see what we already folded in terms of RCG. And we can quickly give that summary to researcher saying, for example: your project is not generating new Gens, or the highest clone number is this or that. Basically this would save us a lot of time in summarising things with new projects and spotting certain trends or problems much quicker.

Thanks
