Remove drupal_add_css() from block module page callbacks - use #attached instead.
Meta issue: http://drupal.org/node/1839338
Patch swaps the string return for a render array, and moves drupal_add_css to #attached.
The last submitted patch, 2003564-remove-drupal_add_css.patch, failed testing.
#1: 2003564-remove-drupal_add_css.patch queued for re-testing.
Manually tested, works correctly. Thanks!
Committed/pushed to 8.x, thanks!
