Show the author's name on each commit.

There was already code to display this, but it was either buggy or
relied on an outdated API response format from GitHub.

There's now a smidgen of padding to the names to separate them from the
commit messages themselves.

setup rspec

the rspec setup is broken, see the docs and the errors for how to fix

https://github.com/rspec/rspec-rails

it will also be necessary to add rspec to the jenkins test run. probably
by adding it to the root rake task
Failing tests for user may deploy based on the permissions array
update capybara and capybara-webkit

the version of rspec we've introduced requires capybara >= 2.2.0.
fix rspec deprecation warnings by moving to modern style

Rationale for the new "expect" style:

fix test (woo! TDD!)
Run rspecs with default rake task
Tests for deploy user only actions

shamelessly ripped off shared tests code from:

http://stackoverflow.com/questions/14507011/how-do-i-get-rspecs-shared-examples-like-behavior-in-ruby-testunit
All but three redirect tests working

also, if I understand correctly, a post deploy hook is making
deployments. what is the implication for authorization here? will the
deploy permission work for this?
Update readme to run tests with the default task

The default task runs specs and tests.
