RSS feed is not customised so remove it

It was commented out in b039041f40de9eacccb5c1f5284ebe1a24197e6e but
it's messing up our Rails tests so I'm lazily removing it for the
moment
Update Rails wording

PHP wording was changed in 2c63296a
Update default Rails header

It was fixed in the PHP version in a4b87b877f2bf5d56e5432839d1c41a44c8d123a
Add failing test for policies#show
Add a static version of policies#show
Add failing test for second policy
Add a second policy to the test database
Remove default house from the URL in a different method

So that we can include it if we want to by calling division_path
explicitly
Add dream ID parameter
Add display parameter
Add more sensible name for policy ID
We need to specify the house as well to get the correct division
Add a bunch of friendlier attributes & methods
Make (most of) policies#show dynamic
Note what's left to do
No need to have these on separate lines
It feels like we should be asking for divisions, not this weird intermediate class called policy_divisions
Add the ability to find out what vote the user selected for a policy
Pass the object instead of it's ID
Port directly from PHP
