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.
