TypeScript support

[appsforartists]

If I point doclets at src, I get this:

Error: ENOENT: no such file or directory, open '/usr/src/app/lib/7ea90b80-bf77-11e6-895d-f541a01addf8'

If I point it at dist, I get a bunch of comments with no signatures

For comparison, documentation.js doesn't know how to read .ts files, but it shows their interfaces correctly if you point it at the generated TS file.
