Added initial files for rspec testing

Includes spec_helper, factories (copied from surveyor) and
first rev of surveyform_controller_spec.rb, including an initial test
for index.
Add will_paginate gem

	Gemfile/Gemfile.lock added will_paginate
	Provides pagination of long lists in index views, etc.
Added template field to index

	add_templates_to_survey.rb: added a template field to distinguish
	between templates and surveys.  Templates are meant to be the
	starting point for surveys, and are not meant to accept responses.

	schema.rb: records the results of rake db:migrate, which will have
	applied any changes from the Surveyor gem plus the above migration.
Added Surveyform model, view, and controller.

Surveyform model inherits survey, a model in the Surveyor gem.
It facilitates the Surveyform controller and views described below.

Surveyform views and controller act against the survey model inherited
from surveyor.  The surveyor controller, which also acts against the
survey model, comes with the surveyor gem, but seems intended to be
used for taking surveys, rather than constructing them.

Surveyform views and controller are meant to help construct surveys.

	surveyforms_controller_spec.rb: includes test for index
	surveyforms_controller.rb: includes index only for this commit.
	surveyforms/index.html.erb: has non-working links for show, edit,
	delete, and clone.
	surveyform.rb: adds search functionality
	routes.rb: added surveyform routes, including those for later
	functionality.
Added some styling

	surveyor-gui.sass: added this file
	index.html.erb: changed some formatting
