Changes to allow headless webkit to work in Jenkins on Ubuntu
Clean up sample postgres settings to work better out of the box.

The Mac homebrew install of PostgreSQL and the Ubuntu package
use different locations for the unix domain socket. If we specify
the socket directory as /tmp, that works on Mac but not Ubuntu,
which expects /var/run/postgresql.

By omitting the path entirely, the postgres client will automatically
choose the correct socket directory path for each environment. Win!

Run rake rails:update:bin per Rails 4 upgrade doc
Rails team no longer recommends --binstubs
Remove binstubs!

The soon-to-be-released Rails 4 no longer plays nice with `bundle install --binstubs`. Bundler-managed binstubs are now discouraged. So I'm removing them from source control. Each developer can choose how to solve the `bundle exec` problem (I chose to use https://github.com/mpapis/rubygems-bundler).
