Charles hours

I added an "hours per week label" to the schedule page UI. I figured this would give students an easier and more accurate method of counting up their weekly hours rather than doing it manually. 

Here is a screenshot of the changes I made to the UI:

What is the <br> tag being used for here? If it's simply spacing, I would recommend changing the stylesheet achieve the same effect. Note that we use [Sass](http://sass-lang.com/) which compiles to CSS. Again, as a general rule of thumb, try to see what's already been done. I don't think we use `<br>` tags for spacing purposes, since it's more a styling issue rather than a content one.
