Merge #576

576: Beginnings of generics r=matklad a=flodiebold

This implements the beginnings of the generics infrastructure; generic parameters for structs work and are correctly substituted in fields. Functions and methods aren't handled at all yet (as the tests show).

The name resolution in `ty` really needs refactoring now, I hope to do that next ;)
