Let's make it all pretty, shall we?

We missed a couple directories with previous attempts to turn this on
globally: app/ and libtextsecure/

Not to mention files in places we didn't expect: ts files that weren't
in the ts directory!

This turns prettier on for every file we care about (js, ts, tsx, md)
everywhere in the project but for a few key parts.
