Option to remove the Gfycat separator

[wraithy]

I would have posted this as an idea however I feel like since Gfycat is already implemented it is more of a small adjustment. It would be nice to be able to remove the separator and maybe just make the first letter of each word capitalized (I have already changed the format of my animals.txt and adjectives.txt to title case). Either making the separator an empty string by default or being able to disable it would be nice since you currently can't remove it without modifying the files yourself (which isn't practical if it's running in a container). Adding the option for title case would also be nice and IIRC it is already built into JS (not sure if TS inherits this functionality).
