Solomon Hykes a1754c7e46 Engine: Receiver and Sender preserve Job.Env 
When sending a new job to a `engine.Sender`, the corresponding
`engine.Receiver` will receive that job with its environment preserved.
Previously the job name, arguments and streams were preserved but the
env was lost.

Solomon Hykes c7978c9809 Engine: Env.MultiMap, Env.InitMultiMap: import/export to other formats 
* `Env.MultiMap` returns the contents of an Env as `map[string][]string`
* `Env.InitMultiMap` initializes the contents of an Env from a `map[string][]string`

This makes it easier to import and export an Env to other formats
(specifically `beam/data` messages)

Solomon Hykes 0aeff69e59 Fix stdin handling in engine.Sender and engine.Receiver 
This introduces a superficial change to the Beam API:

* `beam.SendPipe` is renamed to the more accurate `beam.SendRPipe`
* `beam.SendWPipe` is introduced as a mirror to `SendRPipe`

There is no other change in the beam API.
