Feature Request: save any page to Board (read later)

[zuber1979]

add an option/icon/menu entry to save any webpage to Feedly board

Still open. Cross-linking #150, which asks for saving an article from the popup to a board — the same feature, one step earlier.

Both need the user's boards fetched from the API first; this one additionally needs a way to act on the current tab. Worth building in that order.
