* mixnode: Remove layer computation from mixnode
The layer is currently computed locally. This should be moved to
the validator, and the mixnode should find this information via
a query. Until the query is actually processed, we keep the layer
field as None.

* contracts: Compute layer of bonding mixnode
Predictably compute the best layer of a bonding mixnode by putting it on
the layer with the fewest mixnodes and, in case of equality, with the
smallest index e.g. layer 1 is better then layer 3 if both have
the fewest mixnodes.
The layer received from the client app is regarded as a preferred option
and is only accepted if the number of nodes on the preferred layer is not
bigger then the one on the best layer.

* contracts: Add tests for layer selection
Signed-off-by: Bogdan-Ștefan Neacșu <bogdan@nymtech.net>
* mixnode: Upgrade from 0.10.2 to 0.10.3
The config file is changed so that it's only containing the layer if
the layer exists.

Remove the option of a client app to propose a preferred
layer.

Basic support for message chunking and reconstruction. It's now possible to take arbitrarily-sized input and send it through the mixnet. The sending Nym client will automatically chunk the input into Sphinx packets, and the receiving Nym client will then reconstruct the message at the other end.
