Add jQuery.noConflict as part of the build process

[peterwilsoncc]

To make jQuery upgrades easier, apply noConflict as part of the build process.

In SCRIPT_DEBUG / the src folder, noConflict could be included as either a separate file or directly in the HTML following the insertion of jQuery.

Closing, as [36633] wp_add_inline_script would be a better option for something like this.
