Fixes #134: Use units on compare/detail pages

Sets numbers to display as integers
Adds Energy Star to MOSCSSValues
DRY: display descriptions using MOSCSSValues
Use one-time binding for detail values

Keep cssVal undefined for energy_star key in MOSCSSValues
so that it is not added to the filters generated by the
filterBySize and filterByColor helper functions.
