Fix too much unused space on mobile, landscape view

[Zenju]

Hi,

lightbox2 is great, I only have a single issue with it, namely too much unused space on mobile, landscape view:

In lightbox.js I find the magic number "120"
! maxImageHeight = windowHeight - self.containerPadding.top - self.containerPadding.bottom - self.imageBorderWidth.top - self.imageBorderWidth.bottom - 120;

I'm not sure what this is about. I may be wrong, but it seems the only height that needs to be subtracted is the top offset and the "lb-dataContainer" height below the image (45px in my case), thous:

maxImageHeight = windowHeight - self.containerPadding.top - self.containerPadding.bottom - self.imageBorderWidth.top - self.imageBorderWidth.bottom - 45 - self.$lightbox[0].offsetTop;

Now, when my site is in mobile mode, I can set #lightbox "top" to 0:
@media screen and (max-width: 1050px) { #lightbox { top: 0 !important; } }

And everything looks great, with no space wasted:
