Three new easter eggs:
world : Add a world map to your canvas - it is the same world map as used by the CRS chooser
contributors : Adds the contributors json (used to be in docs, now moved to resources/data)to the map canvas so you can quickly see the locations of QGIS developers in QGIS
hackfests : Adds qgis_hackfests.json (in resources/data) to the canvas so you can quickly see the locations of all historical QGIS hackfests. Note the attribute table has other interesting data too.
