scabot git hooks & deploy setup

[adriaanm]

create ~scabot/scabot/.git/hooks/post-receive from https://github.com/mislav/git-deploy/blob/master/lib/hooks/post-receive.sh
chmod a+x ~scabot/scabot/.git/hooks/post-receive
git config receive.denyCurrentBranch ignore

[adriaanm]

either make it a bare repo, or create config as follows (can drop the git config thingy)

[core]
    repositoryformatversion = 0
    filemode = true
    bare = false
    logallrefupdates = true
[remote "origin"]
    url = https://github.com/scala/scabot.git
    fetch = +refs/heads/*:refs/remotes/origin/*
[branch "master"]
    remote = origin
    merge = refs/heads/master
[receive]
    denyCurrentBranch = ignore

done, again -- restarting is still shaky though, but travis ci should again show sbt building sbt on each merged pr

this was, like, the first thing that came up when I started at Lightbend Typesafe
