Add constants for new AppKit versions through El Capitan. I need this to fix `winit`, because Mojave has some new behavior around layer-backed views and version sniffing is the easiest way to detect when I need to handle it. This also bumps the version to 0.18.3. r? @jdm <!-- Reviewable:start --> --- This change is [<img src="https://reviewable.io/review_button.svg" height="34" align="absmiddle" alt="Reviewable"/>](https://reviewable.io/reviews/servo/core-foundation-rs/266) <!-- Reviewable:end -->

Compatibility
Targets macOS 10.7 by default.
To enable features added in macOS 10.8, set Cargo feature mac_os_10_8_features. To have both 10.8 features and 10.7 compatibility, also set mac_os_10_7_support. Setting both requires weak linkage, which is a nighty-only feature as of Rust 1.19.
For more experimental but more complete, generated bindings take a look at https://github.com/michaelwu/RustKit.
