This bring many goodies, including:

* Ability to specify delimiter and weight_column for CSV files:
```python
dtrain = xgboost.DMatrix('train.csv?format=csv&label_column=0&weight_column=1&delimiter= ')
```
* Ability to choose between 0-based and 1-based indexing for LIBSVM/LIBFM files:
```python
dtrain = xgboost.DMatrix('train.libsvm?indexing_mode=1')    # use 1-based indexing
dtest = xgboost.DMatrix('test.libsvm')                      # use 0-based indexing (default)
dtest2 = xgboost.DMatrix('test2.libsvm?indexing_mode=-1')  # use heuristic to detect 0-based / 1-based
```
* Fix a bug in float parsing (issue dmlc/dmlc-core#440)
