Title: enhancements in surface-based voxel selection backend

- better comments & refactoring of volume_mask_dict as suggested by #yaroptic [https://github.com/yarikoptic/PyMVPA/tree/enh/surfing]
- storage of voxel selection results is now done using a tuple of three arrays, instead of a dictionary where each value is an array. This improves h5py I/O performance
