Add @FeignClient support

[pyltsin]

Hello, Thank you for your plugin! It is very cool. And thank you for checking and correcting the previous mr. I know - it wasn't good. I add @FeignClient support and replace navigation-search-box to search-everywhere-box. May I ask you if this implementation is allowed? if necessary I am ready to fix it.

Thanks again!
