The work function should also be included, in case you want to do a retry.

map {
  'err': {
     'description': Same as standard error bindings
     ...

  'deferred': function#
}

Fail is now provided a map as proposed by @apb2006!

The additional argument is populated with a map containing the deferred and the arguments. This will allow a callback to, for example retry if it gets a busy response.

Additionally error handing has been greatly improved. Errors are now properly reported in BaseX, as well as potential bugs. Also, the fail logic has been revised and properly documented in the ReadMe.
