ConfigureV8TestConstantsTemplate => InstallDOMClassTemplate ? (consistency with
installDOMClassTemplate)

[Nils Barth (inactive), 2013/08/27 02:59:27]

This function actually returns a template; most of the install* functions are
void
(i.e., they just install), so this feels different.

"rUNTIME" looks wrong.

[Nils Barth (inactive), 2013/08/27 02:59:27]

It's pretty ugly, because the CG assumes CamelCase, which isn't true for
constants.
This requires a Perl change too; I'll do in followup.
