Title: Fix sti bubbling

Currently the ActsAsFollower::FollowerLib#parent_class_name method only supports a single level of inheritance in STI. We currently have a use case which results in at least a 3rd level of STI and need support to bubble up to the top level when following them. This pull request provides support for bubbling up n levels of STI.

For example:

```ruby
class Band < ActiveRecord::Base
end

class RockBand < Band
end

class HardRockBand < RockBand
end
```
