9938a23cba Fix JSON when object is first to be pushed (#154) 
When pushing an object to the logger, and this object was the first
field added. Zerolog was outputting an invalid json blob, issuing an
extra comma before the object. This patch ensure that JSON is still valid
even if an object is pushed first to the logger.

Fixes #152

1c6d99b455 Add custom error serialization support and provide sane defaults (#78) 
As per https://github.com/rs/zerolog/issues/9 and to offer a different approach from  https://github.com/rs/zerolog/pull/11 and https://github.com/rs/zerolog/pull/35 this PR introduces custom error serialization with sane defaults without breaking the existing APIs.

This is just a first draft and is missing tests. Also, a bit of code duplication which I feel could be reduced but it serves to get the idea across.

It provides global error marshalling by exposing a `var ErrorMarshalFunc func(error) interface{}` in zerolog package that by default is  a function that returns the passed argument. It should be overriden if you require custom error marshalling.

Then in every function that accept error or array of errors `ErrorMarshalFunc` is called on the error and then the result of it is processed like this:
- if it implements `LogObjectMarshaler`, serialize it as an object
- if it is a string serialize as a string
- if it is an error, serialize as a string with the result of `Error()`
- else serialize it as an interface

The side effect of this change is that the encoders don't need the `AppendError/s` methods anymore, as the errors are serialized directly to other types.
