Map All Contacts at End of Contest

[kylekrieg]

Request to map all the contacts in the current contest on a map after the contest is done. The lat/lon is already saved in the database, so this would not require another lookup for location.

Joe Brett issue (sort of). JB wants to have the map TTL = infinity. Also have the ability to map all the Q's logged if NR needs to be restarted.

Potential solution to #58.
