Provide a button to share the tool (do.co/glob-tool)

Feature request

Feature description

We should provide a social share widget-style element on the tool that allows the user to share the short-link for the tool (do.co/glob-tool) via social media or copy the link directly their clipboard.

How the feature is useful

Currently, the tool has very little on it that pushes the user to share it on -- we should encourage users to share the tool so more people become aware of the great developer tools DigitalOcean has.
