ZOC Masternode Stats not working

[deadthings]

Two things about the ZOC Masternode Stats section...

1. They're not showing up currently. I know they broke once before and Owen managed to fix it, but I don't know how.

2. Line 719 of assets/js/main.js should be 6860.16 instead of 7488 since our first reward reduction has taken place. We'll have to change this again in about 6 months or so. Otherwise, perhaps we can pull the standard block reward from somewhere and multiply that by 288 so we don't have to keep manually changing it every time there's a block reward reduction.
