Merge pull request #2 from rnorth/master

AUTHORS file update
moved most of container building into a prepare script. cleaned up builder a little, adding support for profile.d and default process types. also a new start script -- in a new location, so dokku needs to be updated
cleaner output. always make .profile.d. put old buildpack release config_vars in there.
updating docs
minor readme correction
these should not be in here
prepare script now loads buildpacks. packages are now in a separate file
bad package from cedar
simpler and more transparent container build process
some fixes after running
moved container-build to build.sh, Makefile is just a thin wrapper. renamed build-dir to stack. contents are still placed in /build inside container, but this may change to /stack in the near future
path stuff
these are already in the base image
whoops, this does need to happen after buildpacks
indent docker pull
this is really needed
Play! framework (v1.x) tested successfully with https://github.com/heroku/template-java-play

The inclusion of OpenJDK in the base stack has enabled this.
