Merge pull request #381 from alexanderbeletsky/post-build

Add a post-build hook
For #313: Do not specify both `$APP` and `$IMAGE` for base commands.

As discussed in #313, dokku base commands such as build, release, and
deploy require specifying both `$APP` and `$IMAGE` as arguments where
`IMAGE="app/$APP"`. Thus, the `$IMAGE` parameter is currently redudant.

This patch removes the need to specify `$IMAGE` for these base commands
and is backwards compatible. If, in the future, the base commands expect
and `$IMAGE` different than `app/$APP`, then the `$IMAGE` parameter will
be re-added for those specific commands.

notify user when pushing to non-master branch
Fix edge case: app directory is created before first app push

When an app directory (i.e. `/home/dokku/myapp`) is created before the
app is pushed for the first time (which may occur if config files such
as `ENV` are added before the initial push), then the app directory will
not be initialized to a bare git repo nor will the pre-receive hook be
installed because `plugins/git/commands` assumes that if `$APP_PATH`
exists, then the directory must also be git initialized too. This fix
checks for `$APP_PATH/refs` instead.
