history: Disable lazy loading for the first 42 thumbnails
This speeds up the initial rendering of the page. For a long history (> ~1000 items) the lazyloading JS creates a noticeable delay (>500ms) depending on the cpu power of the machine. Disable lazy loading for the first items so that these are loaded normally by the browser parallel to the scripts execution. Signed-off-by: Florian Pritz <bluewind@xinu.at>
