[WIP] Upgrade to rails master/4.2

I was going to send this when I have the complete set of patches required, but I noticed @SamSaffron has started working on it too, so we should probably share notes :smile:
I upgraded to 2.99 there are a pile of deprecations notices that still need
fixing. any PRs to help fix it up welcome.

3.0 was totally broken so I rolled back.
