Title: implement conjunctions for in_radius queries

This pull request implements conjunctions for in_radius queries. Therefore one can now do:

```ruby
search do
any_of do
with(:coordinates_new).in_radius(23, -46, 100)
with(:coordinates_new).in_radius(42, 56, 50)
end
end
```

This is my first patch to sunspot, so maybe you can point out improvements.
