Andy's Workshop Reflow Oven

Invalid date

• Fix race condition that may lead to the oven being left on if a reflow process is stopped manually.

• Reduce bluetooth traffic and CPU usage by not resending oven duty cycle if it's the same as the previously requested value.

Note that there is also a new ATMega8L firmware version available from github. The new version fixes bugs in the manual reflow option and displays the current oven duty cycle when the android device is connected.
