facets with location data now report their location in the correct format
reworked the handling of data by maputils for better functionality. The new functionality is:
-multiple gps data sources fully supported
-gps data associated with facets is supported
-data points attempt to display on a gps data source that is attached to the same connector
-if they can't add to that datasource then they try the first added gps data source
-if they can't add to that source they try all others
-maps now use the new map styling shown at google I/O

MapTab is compatible with these changes. ClockTab still needs to be updated
all markers on the map now adjust gpsBounds
ClockTab can now use the updated map code
Updated the grapher code to the latest changes that fix the issue where time navigation would get decoupled from the dateaxis
Merge remote-tracking branch 'origin/development' into dev
Updated Grapher code to version that includes the fix for photo channel display
Commented out tests in TimeSpanMapTest.java for now
Fixed problem with flickr photos giving location information when their latitude and longitude is 0

Merge remote-tracking branch 'origin/development' into development
the "no geo location available" message won't show on the map when there is geolocation data available from facets
