Merge pull request #250 from ercchy/master

Fix for travis-ci broke build
remove unused latest_events parameter
add show past events option box on index
udpate past events box style with border
give more padding to events box
even more padding for the past events box
remove latest_events from index tests

This parameter was used in the index view when we displayed cards for X latest events for each country. Now we just display events on the map, so this is no longer needed.
use boolean for past parameter on index
past parameter back to string
append country code to past event link switcher
Merge pull request #252 from ialja/past-events

Add the ability to display past events on the map
remove redundant code

country_code parameter was defined for no good reason in the index view. Getting the country directly from the user_ip seems to do the same job.
remove extra blank line
country_code no longer needed in index view
remove empty line
