Households

I know this is messy - if anyone want to rebase and squash some of this fine - but it is barebones households, a menu entry, new household entry and the relationship between household and neighbors is set up and tested with shoulda 

It should be able to be merged without conflict - perhaps it might be best to merge it into master and then create separate branches for separate views - or any other suggestions are fine 

Also did a few formatting changes to master that sort of grew - broke things but it is fixed now

Will try to be less messy in the future - have to learn somehow
