Added note about move to django-storages
Expose SSL to context processor

This enables the developer to selectively use the secure URL. Currently
the setting is site-wide and this is fine for images but Chrome expects
to get CSS from a secure URL if the page itself is served from one.
Expose URLs to static CloudFiles storage to templates

This context processor allows drop-in replacement of local static
files with a CloudFiles CDN storage. The SSL URL is also provided
as a context variable in case it is explicitly required. In case
some files are stored locally in the STATIC_URL, it can be accessed
through the LOCAL_STATIC_URL context variable.
fixed bug that doesnt work on all python versions on different OSes
Allow container name to be overridden at runtime
Allow importing the cumulus module without configuring it
Added support for setting a custom TTL on the container
Make sure the TTL is also set on the container if it is already public
Resurrected bendavis78's modified_time support to aid with collectstatic
Add an error message and some air between the lines

The NotImplementedError may be confusing without a due explanation.
Also added some newlines to make the method a little more readable.
