Faster scripted test

Problem
-------
edit-scripted cycle is painfully slow right now because `doc`
is really slow (and or crashes after running out of memory),
but scripted tests do not need scaladoc jars.

Solution
--------
This ports `PublishBinPlugin` from sbt/sbt (credits to dwijnand sbt/sbt#2725),
which implements `publishLocalBin`, which skips scaladoc publishing,
and makes edit-scripted cycle faster.
