Subject: [PATCH] Make joystick window always-on-top to avoid Chrome scheduling

Chrome severely reduces the interval of setInterval() calls when a
window is completely hidden (e.g. behind the main Configurator window).
This causes rx loss / failsafe detection to trigger when using the
RX_MSP joysticks
