[core] Add Y.require() AMD-style

Y.require() works similarly to Y.use() but exposes all the loaded
modules as parameters of the callback in order to use ES6 modules more
easily.

YUI().require(['some-es6-module'], function (ES6Module) {
var foo = ES6Module.foo;
});
[core] Change require() example not to use `default`
[core] Use `hasOwnProperty` instead of `in`...

...to check if a module has exports.
[core] Move require() tests to es6-module-tests
[core] Accept a single string as parameter in require()

Y.require() should accept both Y.require(['foo'], fn) and
Y.require('foo', fn)
[DataTable] : Mock `sendRequest`.
[DataTable] : Addition of YUI config.
[DataTable] : Addition of YUI config to example page.
[DataTable] : Upon failure, ask to use the mock instead.
[core] Use lowercase module names in examples
[core] Initialize counter in place
[DataTable] : Mock `datasource-get` instead.
[yui] Deprecate modules list page

All modules list has been posted on this page so far, but because
it is possible to see a list of equivalent even API Docs, the need
for us to provide this page is low now. Fix #619.
