mask error if which jruby fails because jruby is not installed.
This which should not even be evaluated but somehow does on DotCi.

```
$ which jruby
/usr/bin/which: no jruby in (/usr/local/bin:/usr/local/sbin:/usr/bin:/usr/sbin:/bin:/sbin:/home/victorv/bin)

$ [ ! -z "" ] && echo "shouldn't even evaluate past this point" && ln -snf `which jruby` bin/ruby

$ echo $?
1
```

Add read:org scope for github authroziation
This scope has not made t to GHE yet and is unnecessary for GHE but is
needed on github.com to see org memberships.
update docker command options to new style.
Initialize items with default map to avoid LazyBuildMixIn errors in the
console till items get intialized.
