The way chicken bones does it is nice but this allows me to add more
complex and refined dependency download info. Especial since my mods can
normal run across several versions of mc. Eg 1.6, 1.6.2, 1.6.4
Though i will need to recode the depDownloader.class from scratch to
correctly manage this. As well create a way to ensure the MD5 matches up
correctly. Not sure how much it can change from sourceforge to my
desktop.
