run rails server for tests on port 3001
change pid for rails server in test environment

When running in the test environment, change the pid so that two
instances of rails can be run at one time.
whitespace and comments

Replaced tabs with spaces in several places for consistency across
various code editors.  Also the controller method comments in
pa_requests_controller were referring to "request" instead of the actual
name of the resource, which is "pa_request".
removed various requires of spec_helper

Because the rails:rspec generator adds a require of the spec_helper to
the project's .rspec file, there is never any need to require it in any
spec files.

Also, since the spec directory has been added to the Ruby load path, we
don't need to path to the rails_helper when requiring it.
make capybara run test server

This is so that we do not have to first launch the server in the test
environment in order to have the ehr_example_spec.rb pass.
