[BUGFIX] jsfunc.inline is not fully jQuery compatible

When working with TYPO3.jQuery you don't get the object itself,
it returns a jQuery object which contains the mentioned object
at array ID 0.

 * To differ jQuery and JS objects I will add $ to jQuery vars.
 * When using jQuery vars, we should also use jQuery methods
