Fixed: #713: Disply likes and boosts on post cards (#744)

This is a basic and simple way to display them. No interaction possible.

Alos, this patch is not optimised. as everytime a partial post_card is
called, `Post::count_likes()` and `Post::count_reshares()` are called
which means quite a few more quesies are sent to database unless diesel
uses some cache mechanisem.

A way to enhance this this would be to keep a count of likes and reshares
are kept in Post model / table.
