Add page titles to cards
We don't have any system of page titles and I believe we should.
Let's do it like that:
Hive Explorer
on Home page
[BlockNum] - Hive Explorer
on Block page
@[accountName] - Hive Explorer
on Account page
[shortTrxId] - Hive Explorer
on Transaction page
Witnesses - Hive Explorer
On the other pages just keep Hive Explorer
.
