Introduce FitText to resolve text breakage

@fjarrett After some testing it looks like there are still some issues using FitText. There was still some issue with vw units, unfortunately it wasn't a catch all. Longer words still broke improperly.

As mentioned in the previous thread, using FitText causes a flash of un-styled text in the header - which is slightly noticeable on a local install, so I imagine it's going to more pronounced on a remote server.

Other draw backs:

• The hero looks much different than the initial design (Font size initializes at 72.5px instead of 7rem)
• Our breakpoints no longer hold, due to the font-size defined inline on the element.

I'm still unsure of the best solution here. Will have to continue testing.
