Small misc text changes and important change to controller doc 

Can anybody check my change to the "### Setting Content Type" section?

Also, I could not replicate said code in a test project. I don't know if things changed recently.
I agree. I only suggested it because the next line starts with a capital A
and its the only bullet second-level element in the list that starts with a
capital letter.
