Set hit_count on mapping create

At the moment, after you create a mapping, it will have a hit_count of zero,
even if there are hits.

Before we denormalised hit counts onto mappings this wasn't necessary as it
was calculated on the fly.
Allow site import to move hosts between sites

This is useful when we want to split some hosts to a new site.
Clear hit-mapping relationships when moving between sites

If a host is moved between sites, its Hits and HostPaths no longer belong to
that site.

Update all of the gems so that Rails 4 works

- I've probably missed some, but there'll be further updates as I go
  through every error that now exists.
- Rails 4 deprecates the :assets group within the Gemfile.
Fix some errors that came before any red tests

- Not entirely sure what these change, but I've done what the error
  output told me to do to fix the error:

  - Eager load the application only in production.
  - Remove the mass-assignment protection and the whitelist attributes
    ActiveRecord setting - this is done by strong_parameters in Rails 4.
  - Remove the unused ActiveResource config line.
Specify which HTTP methods to call on each route specified by match

- Using match on its own is deprecated.
Make RSpec render_views work again by including a new config line
Require 'rspec/expectations' and 'rspec/mocks' in spec_helper.rb
Remove deprecated specifying of which error is being raised
Remove the deprecated config.whiny_nils in dev and test
Use the new Rails 4.0 syntax for scopes
The use of stub (in some cases?) is deprecated - use double instead
