add beef syntax and tests (#995)
This adds #994 Beeflang. The syntax itself is just a modifed version of c# with a few keywords added or removed. Also Ive added a test and run the test until it worked. I am unsure if the mime_type is relevant to keep in there since I dont know where that actually used. Another thing im unsure of is how the selection of what language/syntax to use for a file actually works aka: Does this actually choose Beef syntax highlighting over Brainfuck if its used on a beef (.bf) file ? for that I would probably need help.
