Removed HekaClient from Logger

* Renamed HekaLogger to just MzLogger
* Need to potentially format msgs as protobuf
Merge pull request #25 from jrconlin/master

Add working Dockerfile and instructions for its use.
Added mux routing.

* removed heka dependency from logging
* up'd version to 1.2
* This version shards by self reporting to an etcd cluster. If a
  given update can't be handled locally, the servers are collected
  from etcd into buckets, servers in that bucket are then posted
  to see if any server can satisfy the request. If not, next bucket
  is processed.
r?fixes

* added mutex to router server list
* added back actual caching timestamp (argh)
* converted back to routing PUT because hobgoblins have left.
* removed storage on routing because redundant.
* fixed error responses for routing.
* Did not add channel based handler for bucket send because I'm paranoid
  about goroutines not being collected and bucket_size should not be in
  the 100s
Removed pk reference
