Support for Typescript

[du-dung]

• What's the file's extension?
  .ts

• What's the file's Uniform Type Identifier (output of mdls -name kMDItemContentType /path/to/your/file)?
  kMDItemContentType = "public.mpeg-2-transport-stream"

• What kind of preview do you expect? How can it be generated?
  I wish it looked like a javascript file.
  As far as I know, typescript started from javascript, so I think it'll probably be made similar.

.ts is also a video format container. The ContentType generated by your terminal output is actually "right", but also wrong because you want to support "application/x-typescript", "text/x.typescript" or "text/prs.typescript"
