How to build sbt on top of Scala 2.11.0-M8

README.txt

1. Run `publish-local` for sbinary from 5af79a0f833d2f0ccf8cc791c2f15f984fb80cc8 (latest master) with sbinary.patch applied.
2. Got to sbt checkout of 0.13 branch (4ab8074753695665300b692a4fee26635b1ed118) and apply sbt.patch
3. In sbt console `++ 2.11.0-M8`; compile
