[ELPA] Add embark

[Philip Kaludercic]

Hi,

I'd like to propose adding the "embark"[0] package to GNU
ELPA. Functionality wise, it describes itself as "sort of right-click
contextual menu", and it seems to have attracted a lot of attention
recently.

The only issue is that all but one contributor has signed the copyright
assignment[1].  Yet Protesilaos Stavrou claims his contributions do not
amount to a "significant contribution", and thus should not block the
addition of Embark to GNU ELPA[2]:

If this is true, I would take care of adding Embark to GNU ELPA.
