Since CACHE_CLASSES is defined in the development environment, also use
it in test to be consistent.

For many frontend developers, code reloading is unnecessary and creates
more problems than it solves.

This commit adds a CACHE_CLASSES environment variable that can be
defined to disable code reloading. We do this as an environment variable
because this variable is most conveniently defined in the
`development.rb` and isn't needed in production.

shared HAML template for both of these.
