Couple of bugs and workarounds.

So after burying myself in this new Icon system, and figuring it all out, it is not so bad, and after everyone adjusts, i dont think it is that bad of a thing, but i have got met with some problems.

The first is, if you have an item that does custom rendering, but doesn't sign up for custom inventory rendering, it only gets Icon check call backs on the damage version of getIcon, meaning if you have a dynamic texture based on use time, and has real durability, you cannot animate the texture(custom bows). This might also occur with all items, but I only tested on one with custom rendering.

Also, the font renderer does not rebind it's texture properly, meaning drawing strings on the rendertick can be bugged, unless you bind default.png before drawing with the font renderer. Unicode mode is unaffected. (This may be a bug from another mod, but this did not happen before).
