Conflicts:
	src/main/scala/adept/Adept.scala
play is no longer prt of deps
intermediate commit
moved to multiproject
moved utils out of core. fixed tests
initial version of Tree. Breaks with sbt-plugin!
major rewrite. now you can build trees with configurations, exclusions, ... just like in ivy
disabling logging (it kills perf)
now we do recursive adds with ivy
fixed downloads
streaming sha1 calculations - gives a 2x perf boost
adding repositories (fixes sample)
split sbt classpath task into 2: generate tree and download files + generate classpath
moved repositories to repos dir. this way there is no directories like artifacts in the same root as the repos
feature parity with ivy
fixes ConflictResolver. Ivy imports are less prone to write multiple times now. Fixed scala version in adept plugin - guess I used the wrong value there...
