Removed all accepts_nested_attributes_for for belongs_to associations because they were creating circular calls in ActiveRecord.

Fixed stack too deep error by commenting out circular reference to sections in the version model. Changed deprecated '.find(:all, :order => 'field ASC')' format to '.all.order('field')'

Migrated codebase from rails 4.0 to 4.2, also removed most of the version specifications from the gem dependencies and ran bundle update
