Move Plot Keywords off the main page as they can be spoilers

@Peter_pbn​ That is correct that the reference view lists the order of up to 5 keywords without regard to "relevance" ratings.

However, the order of keywords listed on the reference review is not always dependent on which keywords were added to a title first in time. Rather, the ordering can be somewhat random.

You may have noticed when you add keywords to a title that only has a few keywords, all with zero relevance ratings, sometimes your newly added keywords are displayed at the top of the keyword page, while other times in the middle, and still other times at the end. I have not yet figured out how this ordering is determined, but it seems to be largely random. The chronology of when keywords are added does seem to be a factor, but not the only factor.

Anyway, it is that (likely largely random) ordering that determines the up to 5 keywords for display on the reference page, without regard to relevance ratings. 

I used to be annoyed by this (because as you point out it is pointless), but over time I have gotten used to the different ordering on the reference page versus the keyword page, which can often give me a new perspective on a title's keywords when I prepare to "audit" them. I might notice different things when I look at the first 5 keywords on the reference page than I would if I look at the first 5 on the keyword page. 

Either way, I wouldn't mind if IMDb were to fix this so that the top 5 "most relevant" keywords are displayed on the reference page. But I'm not going out of my way to ask for that change.

I also don't endorse the idea initially posted in this thread about removing keywords from a title page. I like having them on there. But I don't feel strongly about it either way.
