enable deployment to relative path
- delete cruft from config.ru
- make another absolute href relative
- if env variable RAILS_RELATIVE_URL_ROOT not set, make default app location '/'
- on local machine, assets map correctly to the subdirectory when RAILS_RELATIVE_URL_ROOT specified, e.g.:

$ RAILS_RELATIVE_URL_ROOT='/foo' rails server -p 3000

But not certain it will work in production.  Lots of problems listed here: https://github.com/rails/rails/issues/4308

- still need a test
specify default deployment directory of '/' with ENV.fetch not ||

Don't use BUNDLE_JOBS for now

Install fails in Rubinius when bundler runs with more than one job. I
tried to figure out how to make the matrix work to allow BUNDLE_JOBS=4
for all the other rubies, but I couldn't get it working.

Locally Rubinius installs with BUNDLE_JOBS=4 / --jobs=4 just not on
Travis. Your guess is as good as mine.

Ping: @rkh and all the fantastic people at Travis.
Only run multiple --jobs if we're not on Rubinius
