Title: Sendable futures

## sendable futures in rust (plus other minor things)

Long time coming. Big thanks to @brson and @nikomatsakis for helping me over some spots where I got stuck.

### Overview

* `Future` is now sendable (and not copyable)
* Important stuff in `core::task` (particular `TaskBuilder` and `TaskOpts`) now uses the `pipes::` family instead of the `comm::` family of messaging primitives
* Misc. test cleanup as fallout from change and duplicate renames of some `core` types that I touched during this minor change

Cheers,
Jeff
