tidies up the home page, and gives it a bigger map

- makes the map large enough to show the little Google location popup
- makes the map 100% wide because it's prettier that way
- makes the text above and below the map sit in the pdx blue color to harmonize
- labels pdx blue as such in less
- makes h4 larger than p for readibility
- removes the "Resources" label in the footer; it seemed self-explanatory
- made the footer text smaller for more text hierarchy
changes the double-hyphen to a legit em-dash

cuz typography matters.
