This release includes many changes from different unofficial releases and is also the first official release
which I feel is ready for day to day use.

* Add colored human readable ConsoleFormatter, which is used with the default stream handler.

* Add mucho documentation.
* Allow to remove and list handlers.
* Allow to pass custom formatter.
* Add a `log` method which receives a logging level, message and objects.
* Support colored console output.
* Add an `event` method which returns a `cid` (context id). The cid can also be passed into the event method via the `cid` flag.
* Add `bind` and `unbind` methods for binding context to a logger.
* Add `set_level` method for setting the logger's level.
* Support changing log level via the `_set_level` flag in `critical` and `error` log levels.
* Support printing a simple message without any formatting (only the `message` field and kv pairs are printed).
* Support passing kwarg type context to all logging methods (i.e. `wryter.error('Message', k=v)`.
* Add OOB support (with optional dependencies) for Elasticsearch, Logzio, Syslog and File handlers.
* Expose handler configuration via env vars.
* Add many tests
* Add codeclimate checks
* Try to avoid exceptions in the logger as much as possible. Instead, display errors or exceptions in the console.
