Tango: updated export workflow, added sketchfab activity, added graph optimization parameters, fixed raw images kept in memory (disabled reexctract words on loop closure while updating memory to be able to create more features for transform estimation than needed in vocabulary), portrait/landscape orientation, updated to Eisa TangoSDK. DBReader: fixed high variance when node has no links (if not the first in the current map id). MainWindow: remove frustums not in the current graph.
