Initial commit for map work

This adds a map to the vendor tab for our app and displays each
vendor’s selling locations on the map.
Fixed activate/deactivate buttons appearing
Added pin bouncing on mouse over of vendor cards
Added map for markets.

Also changed updateMarkets.py to add (real) latitudes and longitudes
and changed “British Columbia” to “BC”.
Fixed padding on market map.
Fixed plural nouns in the case of only one market/vendor
Changed "items" to "item" when there's only one item
Changed the sign-up button to comply with facebooks standards
Added map to vendor details page.
Refactored map to accept a list of locations.

After taking a look at how data is being passed back on the seller’s
page, it makes more sense for the map to be able to accept a list of
selling locations to display rather than attempt to pull these from a
vendor object.
Fixed another pluralized string.
Added map to seller page.

Also caught a bug where dynamically updating the map wasn’t working
since we weren’t clearing it every refresh. This is fixed, but as a
result, there’s now a slight flicker every time we refresh the map
since we first remove all pins before regenerating them. I can’t think
of an easy way around this right now, but if I do, I’ll push a fix.
Fixed a button string bug on location edit.
Changed the style of the splashpage
Made the front splash screen mostly responsive
Changed button formatting
This is magic.

I don’t even know how I managed to fix the tabs, but I think everything
looks good now. I have not yet fixed the xs nav bar.
Fixed xs navbar.
Changed some of the textual content on the splash page
Textual changes to the splash page content and some UI tweaks
