Added cog for random scary movie

[gables]

For issue #9: Random scary movie generator.

Currently picks a random "Halloween" movie. We still need to figure out some kind of list of scary movies to randomly select from.

I am not sure if omdb have by genre in their api.
OMDB seems to though

I think that for the purposes of this hacktoberfest, retrieving a random halloween movie will be good enough.

A solid start, Would approve of this if the bot returned something a bit more visually stimulating. An embed with a movie poster would be great, if possible.

I wasn't aware of themoviedb, but their api is way fancier. Thanks for the tip

Switched from omdb to tmdb's api for the advanced search filters. !movie also now embeds the movie poster + info instead of just linking to an outside website.

That looks good!
