Capitalize all table headings

Make sure headings spell "Title" and not "title"

Hi Rolando, I looked around and all table heading strings that I've seen start with a capital letter.
One thing that might have to be modified is the few titles made by more than one word:
"Workspace name" -> "Workspace Name"

Is this needed?

I can go either way (capitalize first letter and proper nouns, like the British; capitalize all words except prepositions, like Americans) as long as we are consistent.

Fixed on trunk on all pages that I could see (used all caps since the page links use that convention)
