#1049 Make votes more visible and informative

[Ahasuerus]

As of Saturday morning we had:

    1,317,500 titles
    9,555 titles with votes
    382 titles with 5 or more votes

Considering the fact that we don't display the "User Rating" value unless we have 5+ titles on file, our voting data is largely hidden. Perhaps it would be better to always display what we have. The original concern was that it would give undue prominence to unrepresentative votes, but it could be mitigated by displaying the number of people who have voted for the displayed title. Something like:

    User Rating: 8.65 (17 votes)
    User Rating: 5.00 (1 vote)

Also, calculate an additional "Combined User Rating" across the main parent title and its variant titles.

edit/submitvote.py 1.5

Installed in r2017-253 on 2017-06-21. Keeping open since we still need to add the combined vote including variants.
