Registers a partial that will be made available to all templates.

A partial is another template that can be used to render part of a larger

render the headers and footers.

Partials may be specified as uncompiled template strings or as compiled template
functions.

@example

Y.Handlebars.registerPartial('header', '<h1>{{title}}</h1>');
    Y.Handlebars.registerPartial('footer', 'Copyright (c) 2011 by Me.');
