Code Standards cleanup

Hey gang,

I've gotten really good at tracking code formatting issues. Today I turned my attention to this module and was able to reduce the code formatting violations down to 6.

The remaining ones would probably be best done by you as it requires knowledge of the variable's purpose and changing SimilarContentController so that it injects the Term service instead of calling statically.

Would love to talk about this module and what it will take to get it stable.
