Remove 'Delete Project' from inside model-level drop down 'Delete Button'

[pjcross]

User commented that he almost deleted his project accidentally while trying to delete a model and how dangerous it was to have the two choices so close together in the drop down list. Watching him work, later on he almost did it again. I also noticed that even in deleting models, he was clicking through the Are You Sure prompt so quickly that I don't think it would actually work to prevent calamity. I think that the best way to avoid this problem is to only allow project deletion from the project-level page (where model deletion isn't available).
