Title: Added config.connection_class

Added the ability to define which class to switch the connection of.

Real life example: app that has two databases, and you only want to switch to connection for the second
```ruby
Apartment.configure do |config|
config.connection_class = Model
end

Model
establish_connection :foo
end
```
