Bug/aitool 4

This is to fix the bug at AITOOL-4. (I was unable to get isites to POST, the form was being submitted via GET, so the max length of the form fields was ~2000 char total.)

I fixed this by using ajax to submit the data and then forward the user based on if it was a submit or draft-save.

I believe there is an underlying problem with using Yii within iSites, but I was unable to figure it out.
