Backlight handling: * Added 'Caption Backlight' and 'Backlight On When Charging' for the iriver remote LCD. * Enabled the backlight code for the simulator, and prepared backlight simulation. It's only a stub atm, writing messages to the console window. * Added tick task handling to the simulators for this to work. * Code cleanup in backlight.c, less dead code.
