Increased photo title max length from 30 to 200 with support for this in the photo display

Photo titles can now be very long with a cap currently set at 200 characters. This fixes the photo portion of #144.

This pull request adds a new `footer` area to the layout which allows for more flexible display of long strings of text like photo titles. This footer is styled to compliment the overlays on the photos and albums when in grid view.

This new layout works all the way down to mobile and works well when small devices are in landscape mode as the title and it's transparent overlay are on top of the image.

Please let me know what you think and if any change should be made!
