* renderPage method is available when using the assets mixin, renders a full page inside the outerLayout, useful for things like password reset pages that are not related to the page tree at all
* Explicit file extensions are allowed when rendering templates; doesn't have to be .html; still adds .html automatically if not specified, so fully backwards compatible unless you were doing double extensions
* New "loginBase.html" template provides good generic markup for tiny interactions like logging in, requesting a password reset, etc. Default version of "login.html" extends it without changes; sandbox has a version that extends it and overrides the hint blocks; people module has templates that override it for password reset, etc.
