NF: RandomClassifier (Random and RandomSame in warehouse)

Primarily for testing or to quickly check if there is no inherent
problems with the method (e.g. double-dipping)

Merge branch 'master' of github.com:PyMVPA/PyMVPA

* 'master' of github.com:PyMVPA/PyMVPA:
  RM: removing untested/unused ismooth
  ENH: boost pymvpa_hdf5_version (and use string) and store __pymvpa_version__ as well
  BF(workaround): for introduced since 2.2.0 release pass_attr - define also at class level
  BF: for the HDF5 storage, we are doomed to stay consistent also with public/private attributes
  RF+MSC: switch off pickling of internal surface objects, because in the current implementation this comes with a significant speed penalty. TODO: see if these can be stored more efficiently
Some bits to centralize import logic in HDF5

and deal with weired cases of our own history.
Merge pull request #211 from hanke/hdf5_history

install mvpa2.cmdline
BF: comment out 'where stopped' marker in tutorial so we could build
DOC: tutorials -- missing import, disabled for now running BayesConfHyp in unfinished tutorial (waste of tim atm)
ENH/RF: allow for combinations among sa specify conditions in GLM modeling for eventrelated_dataset
BF+ENH: fixed up the doctest and added few more rudimentary tests

also now we can load/use 25mm voxel dataset for tests
DOC: Event-related modeling tutorial
DOC: Minor doc polish
DOC: Split spatio-temporal SL in its own part.
BF: rst2ipnbpy -- embed hyperlinks correctly, skip some cells (e.g. note that it is avail as ipython notebook)
DOC: minor tune ups in datasets and other tutorials
BF: Syntax error that degrades doctest performance.
