This release fixes a bug where the watchdog resettet the chip under certain conditions.
To be more precise, I thought that power_manage() terminates on every event, and thus fed the watchdog only after power_manage() in main.c.
Turns out that simple radio events wake up the chip, angering the watchdog. Yet, power_manage() doesn't return for those, so the watchdog is not fed.
Now the watchdog is also fed on radio events.
