v5.1.2

This is patch release 2 of the dcrdata 5.1 series.

The following items are addressed since 5.1.1:

• Full compatibility with Go 1.13.1. fed08ef
• Build system/npm: patch eslint. 311c896
• Fix open redirection in post method used to enable dark mode when JavaScript is disabled. dd3c2ed
• Insight: Socket.io users who are subscribed to an address "room" previously only got transaction event notifications if the relevant address was paid to by an output. The address room should trigger event notifications if the address appears in one of the previous outputs for one of the inputs of a new transaction. Also prevent multiple duplicate notifications for the same transaction if the address appears in multiple places (multiple inputs, outputs, or both). f8b9c05
