Set a header on responses instructing the browser not to cache.

Key: MGNLIMG-103
URL: http://jira.magnolia-cms.com/browse/MGNLIMG-103
Project: Magnolia Imaging Module
Issue Type: Task
Reporter: Christopher Zimmermann
Assignee: Christopher Zimmermann
This is a "quick fix" so that images will be updated in the admin interface and
on the website pages after they have been altered. It is possible to replace an
image with a new image, or to edit an image via cropping or another
transformation - and currently these changes are not visible because the
browser has the old version of the image cached.
After minimal investigation I think the header is:
Cache-Control: no-cache
The plan is then as a next step to always append a date (or date derived key)
as a querystring to images of its modification date, so that versions of the
image can be cached by browser and proxies.
