Merge pull request #50 from dgryski/master

Fix go test
Update README.md
removing buildstep submodule and replacing it with the buildstep script that dokku actually uses. the buildstep project is otherwise completely separate other than the artifact it builds (the progrium/buildstep container)
excellent CI system catching my mistakes
irc notifications
exiting with 7 means could not connect. adding sleep to give container a second to spin up
poor man's retry
source based roadmap file dropped in favor of issue tracked roadmaps. for example: https://github.com/progrium/dokku/issues/55
fairly major refactoring. consolidating code into dokku script. also, went back to installing docker from ppa
hopefully get travis to test this particular branch
nope, no luck for testing branches
forgot to offest args vars
ppa still 0.4.6, so no luck testing 0.4.7 easily either
rolled into dokku
only run travis for master
initial attempt at plugins
forgot how to use wget
using absolute path for plugins
