./tbtc: News for tBTC, Stuff that Matters

[liamzebedee]

My first whimsical branch title 😸

This introduces:

• a NewsItem component
• a Lorem Ipsum Ropsten announcement built with NewsItem, hard-coded URL

Closes: #181

Another note: this won't ask for Web3 perms if you visit it. Just thought I should note that, because it is part of the dApp code.

Screen:

@Gluzman I'm sorry but I couldn't get the news item header to be pixel-perfect 😢 Something silly with CSS baselines and text.
