No way to install or port the stock one?
id consider 2 camera apps "stock", the google camera and the aosp camera. the google cam used to be like the aosp camera, but with photosphere. all you have to do is grab an older apk and install it, making sure that the new google camera nor aosp camera is installed.

ok, i figured it out for you.. make sure that you dont have a google camera nor aosp camera installed, or in /system/app/ nor /data/app/, then flash this in recovery
http://goo.gl/orWkC0 if, for some reason you boot up without the camera, go to /system/app/ then push on the camera apk and install it. i tried, it works.
