Formatting books on person bio
This fixes DIR-129
I'm just going to throw these fixes in too...

* Setting a min-height to .fw-content in case it is empty. This looks a little better
* Turning off fade and scale animations for now on the memberships toggle.
Updating title to be in the format [page] | [category], Biola University
Removing remaining service code.

We deleted the service model a while back, I guess this code just never got deleted.
Removing secret_token from settings.yml.
This is getting overwritten in settings.local.yml. We are starting to default this to blank so that no one forgets to do this in the future.
Updating rails to the latest 4.0.x
Show what departments a person is part of
DIR-121
Add support for customizing the section class.
This gives you more control in the stylesheets to target specific sections.
Listing groups if a person has any.
This completes DIR-132
I also made the departments section up top list all departments.
I was going to just have the memberships section list both departments and groups but we decided to keep them separate for now.
