Allow broadcast packets to be sent directly instead of via the MST.

Browse source 
When the "Broadcast = direct" option is used, broadcast packets are not sent
and forwarded via the Minimum Spanning Tree to all nodes, but are sent directly
to all nodes that can be reached in one hop.

One use for this is to allow running ad-hoc routing protocols, such as OLSR, on
top of tinc.
