Closes#5
Addresses #6
changes:
* field Mining Reward --> Coinbase. (actual reward)
* add field Expected Coinbase (expected/calced reward)
this field only displays if different from actual coinbase.
* add field Cumulative Proof-of-Work
* change tooltip 🛈 --> ⓘ . for mobile devices. (hopefully)
* css: make tooltip text bold, so the ⓘ is stronger.
Adds a 'Canonical' field to the /block page.
note: this requires updating neptune-core in order to obtain the field
from neptune-core's /block_info rpc endpoint.
it was also necessary to change 'use neptune_core::<x>" statements to
'use neptune_cash::<x>'
