Abolish the recommendation system

@lyicx#19697 you made Dr_PePee be admin.
he's very inactive.

I agree.

I've spoken with @"elmon"#17 who is already in slower time re-working the current admin policies for applications, but in the mean time and until that goes live, I've removed the requirement (Though left it as an advisory) in the admin checklist.

For senior admins we will still require a single recommendation for the time being, but I think that will long term be removed as an actual requirement in the future, but I'll leave that for @"elmon"#17 to look at.

I do see rec's as an important part of how we work, but I'd like to re-focus how they actually work and make them mean something beyond managing to harass an admin into saying yes.
