EncryptedDateField and EncryptedDateTimeField Broken

[JoeJasinski]

When using an EncryptedDateField, I get the following error:
invalid literal for int() with base 10:''
I think this is because when the ModelForm first renders an empty form, the to_python function is passed an empty value and therefore breaks when trying to do the split:
date_value = self.date_class(*map(int, date_text.split(':')))
(I think) I was able to solve this by adding a test to check if the value is empty in the to_python function. Also, once I added this check, I was able to enter values that match only the string format YYYY:MM:DD. To solve this, I added a form_class to the formfield defaults.

Not sure how to submit patches or changes on Github (still new to it), but here's my changes so far. I can submit in a better format if needed. Let me know what you think....

The above changes work for when the model field is set to "blank=False, null=False". Still working on getting it to work for "blank=True, null=False"

I have a patch with a bunch of fixes and modifications. I'd like to get involved. How do I submit it to you? (sorry, kind of new to github still)

@JoeJasinski I don't have commit rights to the system, but typically people fork the repository, make the changes, and then make a 'pull request' back to the owners of this repository.

Joe, please, fork the repository, modify it and send me a pull request.

But please, add a unittest for the issue.

[JoeJasinski]

Thanks AdamN and svetlyak40wt, I'll update with my changes and send you a request.

As an update, I've forked the code and have added my changes. I'm still working on adding unit tests, but time has been scarse lately. I'll let you know when those are done.
