[development] Changes to capitalization

[Angela Byron]

Actually... you've just made the case for NOT doing titles  
capitalization. ;)

> Content Types (+1 for Titles of Things)

"Titles of Things" would become "Titles Of Things," which is wrong.

So, let's leave it lowercase: the only fully-consistent, non-shouting  
format. Others have outlined a plethora of CSS or PHP styling options  
for whatever output format you're ultimately after.
