Speaker's user field can't be null

[spacedman]

Documentation http://symposion.readthedocs.org/en/latest/speakers.html says "a Speaker may have a NULL user field" but models.py in speakers/ doesn't have blank=True, so the form insists you have a user model for speakers. It's got null=True, but that aint blank=True.

If Speaker management is being done manually, perhaps the invite fields should be blankable too.

Either the docs or the code is wrong...

Agreed it should be blankable.

Would this be a good "difficulty: easy" issue or has this been fixed by now?
