Keyword removal

The keyword "scifi" (scifi (Sorted by Popularity Ascending)) should not exist because it is the name of a genre, Sci-fi (just without the hyphen). If titles don't fall under the genre, they should include "science-fiction-novel" or "science-fiction-fan" if it just comes into play as part of the plot.

Also, the keyword "science-fiction-short-film" (sci-fi-short-film (Sorted by Popularity Ascending)) shouldn't exist because it's a combination of two genres, Sci-fi and Short.
