Image and Glyph Previews are Zoomed in Way Too Much at Startup

```frontend/public/js/app/views/ImagePreview/ImagePreviewView.js``` appears to handle view zoom values. It does a ```radio/RadioChannels``` request, specficially ```RadioChannels.edit.trigger(PageEvents.zoom, this.zoomLevel, this.isZoomIn);``` around line 300 within the ```imageZoomOut``` function. Changing the attributes, ```zoomCount``` and ```zoomLevel``` don't seem to affect startup zoom.

Possible solution:

Create an initialization function that automatically avtivates ```imageZoomOut``` several times.
