Title: Update lib/layouts.js

Errors sometimes carry additional attributes on them as part of the passed error data.
A utility that utilizes it, for example - is called 'errs', which is in use for instance 'nano' - the couch-db driver.

when only the stack is printed - all the additional information that is augmented on the error object does not sink to the log and is lost.

consider the following code:

```
//the oups throwing utility
function oups(){
e = new Error();
extend(
{ message : "Oups error"
, description: "huston, we got a problem"
, status : "MESS"
, errorCode : 991
, arr :[1,2,3,4,{}]
, data:
{ c:{}
, d:{e:{}}
}
}
throw e;
}

var log = require('log4js')

try{
oups()
} catch( e ) {
log.error("error on oups", e );
}

```

output before the fix

```
error on oups Error: Oups error

at Interface._ttyWrite (readline.js:603:14)
at ReadStream. (readline.js:82:12)
at ReadStream.emit (events.js:88:20)
```

output after the fix would be

status: 'MESS',
errorCode: 991,
arr: [ 1, 2, 3, 4, {} ],
