Use Google3 naming style to match new
projects' and open source google projects' style.
Preferred to do this in a massive CL so as to avoid
style inconsistencies that plague legacy code bases.
This is a relatively NEW code base, may as well keep
it up to date.
Test: name/style refactor - existing tests pass

An <item> is a general tag that can override certain behavior. For
instance, this is allowed:
<item name="foo" type="integer" format="float">0.4</item>
Even though without the format attribute, this would be illegal.
