Add Kyle to steering council, make Talley emeritus (#322)

@napari/core-devs, I've always felt that the core-devs list should
accurately reflect the _currently active_ team, and I don't see my
activity on napari returning any time soon, so this PR moves me from
"current" to "emeritus" core developers.

(It also adds a steering council asterisk for @kephale)

 ## Project history
 
 The napari project began in the spring of 2018. It was born out of the shared need for fast n-dimensional image viewing in Python by project co-founders Loïc Royer, from the Chan Zuckerberg Biohub (CZ Biohub), and Juan Nunez-Iglesias, from Monash University. Since then it has grown rapidly to now also provide a graphical user interface to a plugin ecosystem of image analysis tools for scientists to use in their daily work.
