update_channel in live monitoring

[alalbiol]

pylearn2/train_extensions/live_monitoring.py
In line 294 the function name should be update_channel.
Someone changed the name to update_channels and now it doesn't work

Right, update_channel was changed to update_channels almost everywhere, but that instance did not get changed.
Could you submit a pull request to change that line to `update_channels?
Otherwise, @daemonmaker, could you take care of that?

The fix is in PR #1526 @lamblin.

Fixed in #1526.
