Exporting a World-Map

This patch adds the world map exporter. - add worldmap-save.c that writes the html to the file - use Google maps v3 API to put the place marks on the map - add worldmap-options.h to contain some settings for the JS which will make it easier for those to be changed - add save HTML action in the mainwindow user interface Signed-off-by: Gehad elrobey <gehadelrobey@gmail.com> Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
