  ENH: make random.choice size argument default to None and allow tuple

The size argument to random.choice should work like it does for all
other functions in random as well.

  -----------
  BUG: Do not sort new indices in random.choice.

Random choice used np.unique to find new indices when replace
was False and p given. This is wrong since unique will sort the
indices. This solves the bug, but likely not ideal.

Thanks to @alan-isaac for pointing out the 0-d vs. scalar issue.

  BUG: internal call fix in random.choice

An random.random call from within mtrand was done by a call to
np.random.random instead of inside the class. This can possibly lead
to non-deterministic results after seeding.
