Subject: [PATCH] Allow preheating iron during boot logo

Autostart (if enabled) _before_ showing boot logo (rather than waiting for the entire animation to finish). Only heats if the boot logo is on but not infinite (and autostart is set to heat). Heats to sleep temperature or 75*C, whichever is lower, for safety (and if the iron can get to 75* by the time the logo disappears then this really doesn't matter much). This is purely a preheat if your iron is low-powered and takes a long time to warm and so if autostart is set to heat to soldering temperature, it will start heating the rest of the way once the boot logo disappears.
