django.utils.formats.localize() misses support for long

[David Danier <david.danier@…>]

Seems like the isinstance(value, (decimal.Decimal, float, int))-check on line 83 fails to check for long values.

Simple test (german, USE_THOUSAND_SEPARATOR is True):

In [1]: from django.utils import formats

In [2]: formats.localize(10000)
Out[2]: u'10,000'

In [3]: formats.localize(10000L)
Out[3]: 10000L

Patch follows
