Make OnSignal work on windows

[bayerj]

There is an issue with FORTAN libraries replacing signal handlers and not being able to recover them:

The solution is to

Add to climin/__init__.py:

if sys.platform == 'win32':
  basepath = imp.find_module('numpy')[1]
  ctypes.CDLL(os.path.join(basepath, 'core', 'libmmd.dll'))
  ctypes.CDLL(os.path.join(basepath, 'core', 'libifcoremd.dll'))

And then extend OnSignal with

import win32api
win32api.SetConsoleCtrlHandler(self._console_ctrl_handler, 1)

in the windows case.

After that, climin has to be imported before scipy by the user.

Has been added to init.py.
