No color for anticone of selected tip about dagviz HOT 2 OPEN

1. (blue) blocks that have block.acceptingBlockHash should be blue. -- by the way, this property will soon be renamed to block.mergingChainBlock

2. (blue) updates to this property are received via the MQTT notification dag/selected-parent-chain.

Implementation Details:
(colorless) 2.0. the list of blocks in dag/selected-parent-chain.removedBlockHashes should have their property block.isChainBlock set to false.
(colorless) 2.1. the list of blocks in dag/selected-parent-chain.removedBlockHashes should be used to clear the property block.acceptingBlockHash of any other blocks that reference one of the blocks in dag/selected-parent-chain.removedBlockHashes as their acceptingBlockHash.
(blue) 2.2. the list of blocks in dag/selected-parent-chain.addedChainBlocks should have their property block.isChainBlock set to true.
(blue) 2.3. for each block i in dag/selected-parent-chain.addedChainBlocks: the list of blocks in dag/selected-parent-chain.addedChainBlocks[i].acceptedBlockHashes should add the property block.acceptingBlockHash = dag/selected-parent-chain.addedChainBlocks[i]

3. (blue) The selected tip = the chain block with the highest blue score is blue by definition. (actually all chain blocks are blue by definition)

4. (colorless) Any other tip is color-less by definition.

5. (colorless) Any block that has only color-less blocks pointing at it is also color-less by definition.

6. (red) Blocks that are not blue AND are not color-less are red by definition.

With this done, the Highlight New setting becomes unnecessary.
