Map bug fixes and enhancements

[eroten]

Bugs

• ❗ HIGH PRIORITY ❗ leaflet doesn't render polygons until the maps are interacted with! The fix from before does not get along with the deployment ....
• app title needs margins on mobile
• update main navbar/tabs to style guide
• ❗ HIGH PRIORITY ❗ app is having deployment issues again, quitting before maps are rendered, etc. https://metrotransitmn.shinyapps.io/buffer3

Enhancement

• i kind of hate the leaflet percentile legends....would be nice to show the real numbers
• might be nice if leaflet legends could be drug around by users
• consider adding button for leaflet.extras::fullscreen (was slowing things down when I was doing this, so it didn't seem worth it?)
• consider adding mapshot and/or broadband style downloadable map to a tab where individual units can be isolated with the map polygons
• might be nice if leaflet legends could be drug around by users

See #19

@eroten I pushed the v1.0.0 to the shiny server (so exciting to have a lot of those big changes implemented!). And as such needed to add a new bug to the running list here (deployment issues, app is disconnecting before all map rendering can be completed, etc.)
