Describe the solution you'd like

In the spirit of removing options when not needed, Remove the file upload size limit - rely on the server PHP configured limits.

After all, If you want to upload a file larger than this configured limit, then you could just change it - its not really restricting uploads, because when you hit the limit you could just change it

even more... As you can see a 10mb limit is not even used on the upload page of the template manager anyway! The 2Mb PHP limit is displayed
