Refactored/styled Sizes:

For Model, refactored set_sort_order

For Views, general formatting and removed role: 'button' from all views in project

For Controller, replaced update_attribute with update because former doesn't call validations

For Coffeescript, switched from js to coffeescript, fixed indentation issues and provided more descriptive variable names

For CSS, removed custom css from html file and created sizes.css.scss
Merge branch 'style-project-nick' into style-project
