Fix `app.js` crashing issues, currently crashes periodically when retrieving hashrate data from minergate

This is a two-part issue:

• Remove the charts that compare ETH/ETC on hashrate and price.
• Stop querying minergate.com for hashrate (how to calculate), calculate it directly from the node. This may be best done by having grabber.js calculate and store the data in MongoDB whenever it retrieves new blocks. But implementation details are up to you.

@pyskell Yup. I use systemctl restart-on=failure option in order to solve the problem “temporary” 😄

Yup, bakon is ethernodeio.

Just FYI proposals are locked-in/signed up for so people avoid duplicating work/competing on changes.

But I also will have more proposals soon 🙂

I’ll look into your Block.blockTime comment.
