Introducing Like feature

[mflorea]

@surli

I propose to use a modal available when clicking on the button to display clearly this information.

Why a modal? Why not a popover?

@vmassol

I’d have liked to see proposal with like being on the same like as Tags and “created by”.

Same here. Moreover, I really think that the like feature shouldn’t be too intrusive / distracting. It should follow the styles of the rest of the page meta data.
