support text-transform property
Submitted by Daniel Fore

Description
What I think would be super helpful and give developers less of a chance to do something wrong is to support the text-transform property in GtkCSSProvider. But more specifically, I'd mostly like to be able to enforce "capitalize".
In this way, we can enforce that buttons, menu items, titles, headers, etc are always Title Case. (I'm not sure if Title Case is slightly different from the web interpretation of "capitalize" since Title Case doesn't capitalize prepositions like "of" and "to")
