Force Section Assignment

I love this module ... it's exactly what my project needed.

My site is like About.com - broken up into topical sections with one editor for each section. So in my case I want each editor to only be able to add content to their section. But this module out of the box seemed (before I hacked it) to give a section editor the option to NOT assign a section to the content they're about to create. I'm proposing that you add a config option that disables that behavior.

I've accomplished it in a really ugly way already by just removing a line of code in the module that adds the "no section" option. But I think ideally this new feature would do a couple things:

a) allow you to enable/disable the "no section" option freely
b) if it's disabled, don't display the section menu at all if there's only one section that will be selectable

Hopefully this hasn't already been discussed - I did try to look through the other issues.

Thanks
