2015-02-04	Add a lint for writing `#[feature]` for stable features, warn by default.	Brian Anderson	-0/+20
	The 'stable_features' lint helps people progress from unstable to stable Rust by telling them when they no longer need a `feature` attribute because upstream Rust has declared it stable. This compares to the existing 'unstable_features', which is used to implement feature staging, and triggers on any use of `#[feature]`.
