0 Fixing large file truncation in lophttpd

I dont want this to become a webserver blog, but I just fixed
a bug which lead to truncation of  large files (e.g. >1Gig)
while downloading. Stupid bug by using %d rather than %zu.
Its available at the usual location (version 0.85). 

Thanks to the one and only Nico for reporting. Your mad
scientists can now continue to download the star collision avi's.
