Title: Rename 'after' scope to 'following'

I just started using paper_trail and whenever I would try to use `record.version_at(timestamp)` I would get this error:

```
ArgumentError: wrong number of arguments (1 for 0)
from (__DELEGATE__):2:in `after'
```
I tracked it down to the after call in version_at and it seems it's conflicting with another `after` (maybe `Rails::Initializable::Initializer#after`?), anyway just renaming the scope to `following` fixes it for me.

I can't really explain how no one else would have come across since I would assume `version_at` would be called by at least one other person. The version of Rails I came across this was 3.1.1.

Thanks!
