unify fundraising@ and grants@ into grants@
Right now we have two aliases, fundraising@ and grants@, and they go to nearly the same people but not quite:
grants: isabela steph sarah arma sue al jon bekeela gaba pili fundraising: isabela steph sarah arma sue al jon alison erin
I'm going to add erin to grants@, and then make fundraising simply point to grants@.
We've checked with alison and she's ok falling off the alias, since she's focusing on LFP these days. We can always add her back whenever we or she wants.
