Plugin to detect experimental and beta code

Hi! I created a new plugin for IntelliJ/Android Studio to detect code that is annotated with `@Experimental` or `@Beta` annotations and show an icon on the gutter. Can you add it to the list? Check out it [here](https://github.com/fooock/detect-experimental-and-beta-code). The name of the plugin is `Icons for Java annotations`

Cheers!
