Rack-based asset packaging system

Sprockets::Configuration#version

The `Environment#version` is a custom value used for manually
expiring all asset caches.

Sprockets is able to track most file and directory changes and
will take care of expiring the cache for you. However, its
impossible to know when any custom helpers change that you mix
into the `Context`.

It would be wise to increment this value anytime you make a
configuration change to the `Environment` object.
