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
