Added a safety measure against a problem where a node in rare situations would turn itself into a sink. Not entirely sure why this happens, but the safety measure should at least avoid the results of the problem. Added more debug messages.

Improved phase lock behaviour when neighbor is not duty cycling: senders notify receivers via the 802.15.4 pending bit that they are not duty cycling. Neighbors then will start sending packets immediately and not wait for neighbors' phase. Tweaking of ContikiMAC timers to make it more reliable.
