Title: Hyperalignment improvements -- 2nd round

Swaroop wanted to get projection for new datasets, not used to derive the comon space. This PR separates
a dedicated train() form HA's __call__() and makes this possible.

If I look at what is left in __call__() I really think we should make it take only one dataset, and create one mapper. This would make it even more similar to the rest of pymvpa (albeit still returning a mapper).
