change import pwd library for import os in createsuperuser

[Kenneth Belitzky]

the file createsuperuser.py (rev 7590) is using the pwd method to detect default user. while this is good alternative on Unix based systems, this library (pwd) is not included on the windows version of python.
my suggestion is to change this:

try:
  import pwd
except ImportError:
  default_username = ''
else:
  default_username = pwd.getpwuid(os.getuid())[0].replace(' ', '').lower()

with

  default_username = os.path.expanduser("~").replace(' ', '').lower().split(os.sep)[-1]

or something similar, in order to get a windows compartible method too.

(In [14607]) Fixed #7077 and #7431 -- Use getpass.getuser instead of pwd.getpwuid to determine the current system user's username in the createsuperuser management command to enable the feature on Windows. getpass.getuser automatically falls back to the previous method.
