Update client/cpw/mods/fml/client/GuiModList.java

Predefined mod icon size. Then re-size to fit to boundary.
Allows for Non shitty looking mod icons, HD ones infact :3

This GuiScreen does annoy the shit out of me this was one of the things that annoyed me.
Wasn't sure if you would appreciate a remake of your gui so I thought I would just see your opinion on this small feature.
