Teach ALE about cargo features and add some configuration options
* When working on rust/cargo projects of varying sizes, it may be useful to either build all possible features (i.e. lint all possible conditionally compiled code), or even turn off other features for a quicker edit-lint cycle (e.g. for large projects with large build times) * Added a g:ale_rust_cargo_default_feature_behavior flag for instructing cargo to not build any features at all (via `--no-default-features`), building default features (via no extra flags), or building all possible features (via `--all-features`) * Also added a g:ale_rust_cargo_include_features flag for including arbitrary features to be checked by cargo. When coupled with g:ale_rust_cargo_default_feature_behavior this allows for full customization of what features are checked and which ones are ignored
