Less-ize breadcrumb css. Make links orange. Addresses #427.
Add a teaser model

Teaser is a per-language, short description of a page.  I had to
override the ``PageAdmin`` class for Django CMS pages to include the
teaser in the Page admin.

Addresses #426
Added __unicode__ method, docstrings to Teaser

Add a __unicode__ method and some docstrings and comments to the Teaser
model and the custom admin.

Update changelog and docs for teaser feature
Merge branch 'hotfix-426-page_teaser' into develop

Conflicts:
	README.rst

Since the addition of the Teaser model requries a schema migration, I
thought it made sense to make it a new major version (0.6), making the
current development changes 0.7.

Force section list to full width

Set width of the ``#section-list`` container to take up the entire available
horizontal space.  This was the behavior but in Chrome 0.25, the section
list started shrinking to show only a single slide icon.

Supress error for many assets, same container

Catch the MultipleObjectsReturned execption, log an error, and pick one
of the multiple assets so the viewer sees something.

I had to add the section model instance to the context when calling the
``container`` template tag so I could include the section ID in the error
log and make it easier to look up and fix stories when this occurs.
