simple styling to differentiate summary and call-to-action in viewer. wip for #369.
compiled CSS including story viewer tweaks. (#369)
Clean up indentation, line lengths
Added class attribute for translation class

This makes it easier to work with translations.  I had done this already
for other translated models but not for Organization and Project.
Clean up spacing/indentation
Form class for translated models

This is a first pass at a form class that handles the translated fields
as if they were all on the same model instead of spread out between two
models.

I added some helper methods to the TranslatedModel class to make it easier
to implement this.

CreateOrganizationForm is an example of using TranslatedModelForm.

This functionality is needed as part of #458 and #463, but when fully
implemented and tested could help refactor a lot of the translation code.
Skeleton for organization creation view

Begins to implement #458
add a placeholder polyfill script. when included (via Modernizr.load or otherwise) will apply placeholder behavior on document ready and provide a method to apply behavior on demand in window.polyfills.placeholders.
incorporate placeholder polyfill into story builder.
update modernizr custom build to include tests for input attributes (for placeholder support). (addressing #416)
remove console.log for testing placeholder polyfill
add general template support for placeholder polyfill via Modernizr test.
Base form class for translated models

This should have been added as part of 65fb039cfa5ebb248729644275d77a02de26b5ba
Template for organization creation view

This should have been added in 37fe41e292e23ab93fec98464a9423203f29333a
Tests for create organization view

These test basic access control and object creation functionality of the
views.
slightly darker callout sections in viewer
Add members field to organization form

Add a members field to OrganizationModelForm to allow users to specify
users that should be associated with the organization when they are
creating the organization.

In order to implement this, I created a custom field, UserEmailField that
converts a comma-separated list of user emails to a queryset of User
objects.
better styling for "add new section" widgets in builder. includes a css transition. also in this commit is a test for offering an affordance for adding a new section--some subtle styling of the spacer in the non-hover mode.
add word-wrap and overflow-wrap (for future compat.) to call-to-action section on story detail page. addresses #486)
Added image asset creation for Organizations

Images can be uploaded to set the featured asset of the newly created
organization.  I had to add a custom form to support compressing the file
or URL field down to a single value.
