numpy.random.RandomState.

Fix EighGrad that didn't returned the good dtype when the input is float...

Use the real dtype in case of mixed dtype input and work around dtype change depending of numpy version.

This was an error in the buildbot.

Minor fixes (typos)

Fixed a few typos in documentation.

Added allow_gc Theano flags in the list of Theano flags.

Fixed crash in constant folding optimization

This is because either:
- There will never be any client and thus the node will be pruned, so
  performing constant folding would be a waste of time, or
- Someone will add clients later and will re-run the constant folding
  phase, in which case we will want to use the client-dependent logic to
  decide whether constant folding should be applied or not.

Fix tests

Fix for a source of non-determinism

Corrected a few typos in scan documentation.

This can just cause confusion.
