Issue #29 Changed how TileLevel calculate pixel density to make densities more consistent between granules on display. Changed TileSetRenderable level change threshold to smaller value so displays look less pixelated with new pixel density calculation. Fixed FileTreeView from throwing errors if two definitions with same name defined which came to light from NPP build
