[BUGFIX] Ensure jQuery is loaded as well when loading the Lang module

If we forcefully load the JS Lang-module, which depends on jQuery, we
have to ensure that jQuery is requested as well, otherwise the dependency
of the Lang-module fails.

Note that jQuery is never loaded via requireJS. jQuery must be explicitly added
by calling  the loadJquery method of PageRenderer. jQuery itself registers as
an AMD module and can then be used as dependency by other AMD modules.

We therefore also remove the (completely useless) path definition in the
requireJS configuration.
