[Taranis] Asterisk BMP (thanks Martin!)

[Taranis] WDT timeout adjustable when dealing with long delays without pulses (thanks Mike for the trick!)
[Taranis] After USB is disconnected, the SD and the EEPROM are read inside the main, not inside the interrupt
[Taranis] Removed dead code about CPU temperature
[stock] Flash saving (thanks Mike for your emails!)
