Design UI/UX to ease social sharing

[saumyakaran]

Dependency #56

Further improve the UI/UX to include prompts for the user to share their experiences on the platform on various social networks (starting with twitter)

For example: "I just staked 1000 KSM across 16 different validators, expected returns are 16% yearly! Thats 7% more than XYZ bank! See how you could participate on polkanalytics.com". Ideally there'd be a number in the user's native currency, but that's for future iterations
