undo overflow style on trailListColumn so trail navigation works
'MANAGED BY' -> 'MORE INFORMATION'
margins around logo adjusted

now all logos can have the same amount of padding if the uploaded image
has none
updated the activity filter buttons so that the active state matched length (dk blue with white)

right now, the mtn bike is hard-coded in as gray. we probably need to
change this so that once a trail allows mtn bikes, the app displays
this as an option (blue button)
