Fixed a bug in LOD boundaries - changed the way we calculate whether or not to render a parent "average" voxel so that if any of it's most distant child would not be visible, then it's used instead of it's children - added precalculated value for topFarLeft corner of AABox (optimization) - changed VoxelSystem::newTreeToArrays() and VoxelTree::encodeTreeBitstreamRecursion() to use the same help function for determining this LOD boundary behavior - deleted old dead code in voxel-server and VoxelTree for picking which node to start sending with, since it wasn't being used - added VoxelNode::furthestDistanceToCamera() which tells you not the distance to the center of the voxel, but the distance from the camera to the furthest corner relative to the camera. - added ViewFrustum::getFurthestPointFromCamera() which given an axis-aligned box will tell you which vertex of the box is furthest from the camera
