Add alias for parametrize or provide better error reporting

Consider adding an alias parameterize for parametrize, since it's a valid spelling but using it in pytest will give a misleading error message - for the code below error message will say "fixture 'arg' not found", not mentioning that parameterize doesn't exist.

#!python

import pytest

@pytest.mark.parameterize('arg, expected', [
    (1, 1),
])
def test_confusion(arg, expected):
    assert arg == expected

It is quite a confusing message. Another option might be at least adding a warning for common misspellings. I will note that in the meantime, you can sidestep the issue by adding this to your conftest.py:

#!python

import pytest
pytest.mark.parameterize = pytest.mark.parametrize

I just got bit by this too. Another solution would be to move parametrize to a module that isn't generating members automatically, so misspelling it will give a clear error.

Well the release was made today so this would seem to be fixed :)

And here I thought I was going insane. Thanks for the fix.
