Disable Community Rating for Episodes of TV shows

[dezchai]

Changes
Outlined in more detail in the enhancement request #936
Adds setting to disable community rating for episodes of TV shows.

Also, the if statement could maybe be brought out so that it's not nested.

if get_user_setting("ui.tvshows.disableCommunityRating") = "false"
    if isValid(itemData.communityRating)
        m.top.findNode("star").visible = true
        m.top.findNode("communityRating").text = str(int(itemData.communityRating * 10) / 10)
    else
        m.top.findNode("star").visible = false
    end if
else
    m.top.findNode("rating").visible = false
end if

if get_user_setting("ui.tvshows.disableCommunityRating") = "false" and isValid(itemData.communityRating)
    m.top.findNode("star").visible = true
    m.top.findNode("communityRating").text = str(int(itemData.communityRating * 10) / 10)
else:
    m.top.findNode("star").visible = false
end if

Issues
ex. Fixes #936

To Do
A small spacing is left over after the setting is turned on.

For future PRs, make sure to name your branch something informative (instead of the default main branch name of "unstable"). For example, for this PR, I would have named it something like "disable-community-rating" 👍
