[BUGFIX] Reenable JS in Extension Manager

Due to commit https://review.typo3.org/40936/ the JavaScript loaded by
the Extension Manager breaks because jQuery is run in noConflict() mode.

This patch adds a new option within the ContainerViewHelper and
PageRendererViewHelper to be able to set an alternative namespace for
jQuery loading, allowing to have jQuery global again.
