Core - Provide BitmapBrush with the currently active surface

UI - Small style change to the confirmation dialog
Surface - Add API to get an ArtemisLed by its corresponding RGB.NET LED
Devices - Add API to get an ArtemisLed by its corresponding RGB.NET LED
Devices - Add API to get an ArtemisLed by its corresponding RGB.NET LedId
