forms.IntegerField does not support unicode numbers

[Ben Youngblut]

A Japanese user on our site just tried to submit a form with u'５０'
Python's int() function correctly handles it (as well as python's \d+ in regular expressions).
But in IntegerField's to_python the value is cast to a string before being run through a regex substitution to remove ".00000" .

I found a quick workaround I changed it to forms.FloatField and then I cast to an int in the clean_XXX function. (it is just for page number in my case so I don't care if it auto truncates/rounds)

I believe this is just a matter of coercing the value to a text type instead of str to handle Python2.
