Feature googlemaps

Luther College Google maps code and scripts (along with changes fetched upstream from master since this branch was created).

The prefs are still hard-coded, so when you create a default map it will show Luther College preferences.

There is no custom css.

There are two relations, a page_to_google_map and event_to_google_map. Since events.php was not modified use the google_maps page type to view.

This version does not deal with large data sets, rather offloads the task to Google maps APIs instead of using Reason.

Browse to scripts/upgrade/update_google_map.php to run or test the database migration script.
