WIP: add Forward class with repr

To be able to see important information regarding the gain matrix, i.e.:

    In[1]: fwd
    Out[1]: <Forward | MEG channels: 118 | EEG channels: 63 | Source space: Surface with 8171 vertices>

I guess my idea was that it could (in the future) make sense here, but I'll
just let someone else (in the future) worry about that.  We're on our way
to have a few, but will address in the morning.
