New Lit version

[squeek502]

I think it's time to release a new Lit version (and a new Luvit version after that). Some things to do before releasing a new Lit version:

• Make sure the new Luvi release works (Mac/Linux deploy might be failing); EDIT: see Mac/Linux deploy failing luvi#225
• Resolve any conflicts between shared luvit/lit deps (it looks like lit's http-codec and luvit's http-codec are out-of-sync in a weird way, there might be others)
  • Whoops, forgot that Lit uses http-codec 3.x while Luvit uses 2.x, everything else is in-sync
• Bump versions of any changed Lit-specific deps and publish them
  • Need to figure out how to publish creationix/coro-fs or get creationix to publish it
• Bump lit version and publish it (Bump deps / Luvi / Lit versions #266)

v3.8.0 should be fully released. Let me know if anything is not working right.
