Use !== rather than > in condition

This is more aligned to the actual logic we're implementing
although there is no difference in flow.
Add pathIsSSL predicate
Use pathIsSSL for protocalCheck conditions
Add education text
Add h2 to h1 rule
add backers data
pass backers list to upgrade view
add backers array as global
add backers markup
create and add markup for each backer
Begin css for backers section
set width of backers container to 100%
give backer image a class to overwite styles
use class over tag name
prefix selector with #body
Update backer img styles, center container and use fixed widths
Move h1/h2 dont weights to their own selectors, embolden h2 slightly
