Provide an alternative to title in behaviour, just a basic input property

I've been using this module for a few weeks, besides the UI is not perfect is quite useful.

There is a particular issue I see with this module. If you want to create an entity with just a few properties, and you want let users modify those properties, the only way to automatically display the widget in the entity creation form is using a 'title' behavior.

This is ok if you have only an editable property, but if you have more than one, the title behavior is not a good option anymore. You shouldn't have two or more titles for an entity after all...

I have seen some issues when you have an already configured entity and then you need to include another property. If you set this property as a title, well, it will behave as a title, and then you can see entity instances named with the last property added. And also, of course, all the properties widgets are marked as required.

So, I think ECK should include another behavior just for basic input properties. Just a textfield (marked as non-required) that can be customized with a hook_form_alter if necessary.
