Live DAG: side blocks carry their GHOSTDAG colour (blue paid, red excluded, pending)

Browse source 
Observer: additive live_blocks.color (pending by default). Every chain block's
mergeset marks its blues blue and its reds red, from the notification's verbose
data or getBlock for chain blocks learned via virtualChainChanged; a reorg puts
the removed chain blocks' mergesets back to pending. API serves color. Page:
blue side blocks filled in the miner's hue at 70% with the ring, pending the
faint outline, red a dark outline with a strike; tooltip and legend name the
state.
