Drillcore and corebox view updates

[ollehints]

All new box images should come in landscape rather than portrait format for make better use of screen space. Old drillcore images need to be turned 90deg or -90deg.
Thus, in listing boxes in drillcore detail view need updating:

• each box image and info should be on separate row, image in the left and data in the right
• boxes should be aligned left and occupy page with (that is, two cols)
• box numbers and core depths should run from top to bottom (regardless of core placement in the box), check https://geocollections.info/drillcore/486
• box photo date (it should be file's date_created not date_added) should be shown also left to image, to allow successive boxes be close to each other.
• if no image is available for box, a placeholder div should be show, same size as regular box preview (400px width)

In corebox view (e. g., http://geokogud.info/corebox/5541)

• images should be shown below title and above data table
• box image preview should come from medium size file (1000 px) and resize with main data table (to have same width with table)
