b59018aa05 python: multiple eval_metrics changes 
- allows feval to return a list of tuples (name, error/score value)
- changed behavior for multiple eval_metrics in conjunction with
early_stopping: Instead of raising an error, the last passed evel_metric
(or last entry in return value of feval) is used for early stopping
- allows list of eval_metrics in dict-typed params
- unittest for new features / behavior

documentation updated

- example for assigning a list to 'eval_metric'
- note about early stopping on last passed eval metric

- info msg for used eval metric added
