Navbar Porcaro logo updated

Updated desktop and mobile resource for navbar Porcaro logo.

Added 30px padding-right to our people paragraphs to match grey line
above per mockup.
Navigation bug fix

Added T/F flag to resolve navigation bug when going from special
content pages (our people, our process) to portfolio page.
Correct tablet "View All Projects" link and bug fix

Now returns to main portfolio list view, instead of showling that list
below the portfolio item.

Also fixed bug when swapping between portfolio items for smoother
transition.
