Allow preloading of all thumbnails to be disabled #3

With a very long movie, preloading all of the thumbnails becomes network intensive. Allowing them to load on-demand (and fill the cache on hover) should be an option.

How many thumbnails are you loading? For my case the number of thumbnails doesn't really depend on the length of the video, I have configured a maximum number to generate. Thanks.

@tjenkinson I generate one for every 10 seconds of video (so 4 hour video --> 1440 thumbs). Good call on maximum number though; I can easily slice up my list on the client side before passing into Clappr so that you can only scrub through a new thumbnail every x pixels.

Cool ok. A new option to only load on first hover might be useful in case the user never hovers over the bar, so I'll leave this issue open.
