Using ActiveSupport#on_load instead of send :include to boot.

[kreeger]

This is similar to a pull request I made a while back on another project that included itself onto ActionController. In order for this to work on the rails-api gem, and other projects which may not use ActionController::Base, the method for including the ActionController::StrongParameters module should be changed.

# instead of...
ActionController::Base.send :include, ActionController::StrongParameters
# let's use...
ActiveSupport.on_load(:action_controller) { include ActionController::StrongParameters }

Also, it appears my editor has trimmed up some trailing whitespace in the rest of the file; let me know if that's a problem with this PR and I can change it.

I'm new to rails and trying to deploy a rails-api api. I believe this may solve my issue of fields not being written to the DB, but I cannot figure out how to implement this. Could you give a few hints? Seen StackOverflow question: http://stackoverflow.com/questions/19871786/rails-api-post-params-being-set-to-null

👍

The whitespace changes are unrelated and make it difficult to see what exactly you changed. Please limit the change the just the relevant code.

@jeremy I can do that; let me close this PR and open a new one with only those changes.
