Change question accordion toggle icon

[boonebgorges]

On question lists, the accordion toggle icon should be https://fontawesome.com/icons/angle-up?style=solid and https://fontawesome.com/icons/angle-down?style=solid, instead of the current + and -.

I've made the change but I need to have another look at the mockup to double-check the styling before it's ready to verify.

Looks like it's not fully indicated in the mockups just how it should look - here are screenshots of what I've built. Let me know if this is what you had in mind. (cc @jennaspevack - see the icons in the upper right)

Looks good to me!

Awesome, thanks!
