merge view_history and view_post views into one

it's a little odd to have two similar-looking pages for two pieces of information
about a post, when we can combine the two quite easily.
the ux feels a lot nicer now these are in the same place.

this also fixes the inconsistent permission checks i mentioned on xmpp.

featuring a ridiculous name for the actionbutton, to avoid any choice
of name distracting from the main changes.
