Now we do not have separate AMD builds, instead we use a UMD wrapper
to support both AMD and CommonJS environments along with the browser.
This has been tested with RequireJS and it correctly imports Select2
and hooks into jQuery.
This means that all builds will include the Almond AMD loader, but
this isn't that much of an issue when you consider the file sizes.
The loader is namespaced so RequireJS and other AMD builders don't
complain about `require` and `define` existing. This is also done
so AMD loaders don't conflict, as Select2's AMD loader should
operate independently of others.
There are now two layers of wrappers that are applied to files,
only one of which is used for the translation files. This allows
us to only load in the internal Select2 modules once, and in
general makes most things cleaner. These have also been pulled out
into individual JS files instead of being stored in JSON files,
allowing us to add comments and make things look readable.
Because we use a few hacks, these files are heavily commented as well.

We don't need to update the dates on these every time that grunt
is called. This gives it a much more basic banner that is similar
to the minified version.
This adds a check that triggers an error if Select2 was not able
to detect a copy of jQuery on the page. This should help users when
they are setting up Select2.
**Breaking change:** The full build no longer includes jQuery.
Previously, the full build included all requirements for Select2,
including jQuery, which meant that anyone looking for the optional
requirements had to possibly include multiple versions of jQuery
on their page. This means that anyone requiring Select2 to also
bundle jQuery will now need to include jQuery on their pages
alongside Select2. A copy of jQuery is included in the repository.
**Breaking change:** The AMD build of Select2 will now correctly
wrap the code in a `define` block. It will still create the named
blocks inside of the code, which should be valid in most AMD build
systems, so now Select2 is compatible with cases where the file
does not have the same name as the Select2 module name.
**Breaking change:** Select2 will re-use the AMD methods if they
are available on the page, but it will not longer leak the included
AMD loader to the global scope. The AMD methods will still be
available on the `jQuery.fn.select2.amd` namespace.
The `mock.js` test file has been renamed to `helpers.js` and will
handle the escalation of the `require` and `define` variables to
the global scope. It should be included in all test files, or the
tests will fail.

When `jQuery.noConflict` is called, the global `$` variable is not
defined. We cannot assume in the code that the variable is defined,
and instead should always make sure to import the `jquery` module
when we need jQuery.
This fixes all of the issues where we are assuming that `$` is
defined globally when we are not importing the module. This also
fixes the issues when defining the `jQuery.fn.select2.amd` modules
where we were always attaching to the `$` object instead of the
`jQuery` object.
