Subject: [PATCH] Add default configuration for images (#1979)

This patch allows configuring image processing instructions
for all images.
A use case is generating a fixed set of sizes (derivatives) for
all images, without having to specify them in the content markdown.

Example configuration in user/config/system.yaml:

images:
  defaults:
    derivatives: "[300,600,1200]"
