Merge gfx-rs#163

163: Remove Rust wrapper and examples r=kvark a=kvark

Fixes gfx-rs#160 
Closes gfx-rs#60

Everything specific to Rust API is about to be moved to https://github.com/gfx-rs/wgpu-rs
It would let this project to be a proper mirror of mozilla-central piece, and it would encourage other authors to experiment with different approaches to Rust wrappers (i.e. borrowing versus non-borrowing).
