Added reduced repl test.

Also moved some code that would make these tests easier to setup into
the repl_util module.
Added some precondition tests
removed unneeded test.
updated repl works test.
Added test for proxy get of reduced objects
Added test for always reduced objects.
various fixes for cluster_mapping

changed cluster mapping to correct nodes.

fixed logging

a few more fixes aimed at getting closer to passing

added test for issue 306, decommissioned cluster redirection

changes to support use of ring meta-data instead of ring for mapping config

changed to use riak_repl_console:block_provider_redirect/1 for configuration
added test for delete_block_requestor_redirect
fixed API to add redirect on LeaderC
reverted to master
Add test for CRDT convergence.

This requires a build of Riak using:

* basho/riak_kv#650
* basho/riak_pb#52

riak_test should be built with:

* basho/riak_pb#52 (same as above)
* basho/riak-erlang-client#114

This test follows the same outline as the verify_counter_converge
test, which is to:

1. Write a new datatype into the cluster.
2. Check that the value was correctly stored, via connecting to some
   other node.
3. Partition the cluster.
4. Perform updates on both sides, verifying that the new values do not
   cross the partition.
5. Heal the cluster and show that the data converges according to the
   desired behavior.

There is still one outstanding problem with this test, in that maps
have a "reset" behavior when removing a field; namely, embedded types
would be semantically set to a value that resembles their bottom
value, but is actually higher in the partial-order/lattice. We have
decided this behavior is too surprising, especially in the case of
counters, where concurrent reset-removes would result in a
double-counting problem. See L255 for an example.
update README
Fix copyright date.
Use a wait_until when checking the value.
Use create option on all modifications in case the preflists come out strangely.
Merge pull request #381 from basho/jrw-readme-updates

update README
Make RT wait until the nodes actually detect the partition.
merged uack test into rt_cascading.erl
added configuration for 2 1.3-only tests
removed 'true' clause in test activation case statements; replaced with wildcard.
