Provide bloop incremental compilation.

Though it is not directly Wake issue. But currently Wake flow is slower than sbt flow for daily debugging (lots of small modification and re-compile).

I've transferred this issue to the best place to track it.

I completely agree this needs to be done. I spoke with the Bloop developers and they told me it requires some improvements to Bloop. To summarize:

• We use Bloop as a one-shot CLI instead of client-server architecture because Bloop currently uses unauthenticated local ports so it doesn't really work in multi-user environments
• The developers think it is relatively easy to make the Bloop client support named pipes
• They also said it would be too difficult to make the one-shot CLI work with incremental compilation

I second multi-user mode is more important even than compile speed. We have met the problem that one machine can only have one bloop port and one user can benefit from the service. So even InteliJ IDEA support bsp mode, but we finally did not use bsp. Still use sbt or wake.
