Upgrading tries to upgrade Django

[jonasvp]

This is a small thing but somewhat annoying: everytime I do an pip install -U django-filepicker, it tries to upgrade Django as well. This seems to be because in setup.py it says

install_requires=['django']

Can we assume that anyone using django-filepicker has Django installed? That would make upgrading with pip go much more smoothly...

I'll add a version number which should solve the issue

Don't add a version number. Instead, please take out the Django from the install_requires.
