Merge remote-tracking branch 'origin/develop' into develop

* origin/develop:
  Fixed the progress bar when uploading not properly showing up
  Removed log statement in timeago filter.
  Changed how the date parsing occurs for the filters to be able to support more browsers. This should also be a bit safer than the original code.
  Empty cms properties don't default to the placeholder text correctly, so this uses the placeholder blank image for the homepage about banner.
  Removed homepage about image from the cms properties to force a more obvious  placeholder image because the previous image wasn't quite good but wasn't obviously a placeholder.
  Uncommented the image tag on the homepage about banner. There is still no proper image that currently fits the area.
