status clickable (this also fixes multiple dropdown being openable at the same
time)

on scrollable areas

all statuses/accounts to assemble, but at least lists don't have to be
re-rendered all the time now. Also add "mention" dropdown option

Also fix reloading of timelines after merge-type events

entire timelines (only fetch since last known ID). Side effect: account
timelines no longer update in real-time

Also upgrade react-redux to latest version. This is a performance update

Also, only update relative time every minute instead of 6 seconds. My bad

Track relationship in redux state. Display follow/unfollow and following-back
information on account view (unstyled)
