Issue and fix for sorting large list of config options

[bcatherall]

We probably have about 200 config options in Behavior, and the unsorted list was just too much to manage.

It was really simple to make it a sorted list.

line 40 of lib/behavior.rb

change from meta.keys to meta.keys.sort

Sounds good and makes sense. Shoot me a pull request and I'll make the change!
