fixed issue #5

## properties exists in:

* jQuery.ajax 
* options-argument (xi:include) => animate / fadeIn / fadeOut / fadeToggle / hide / show / slideDown / slideToggle / slideUp / toggle

I'm sorry if the code is a little bit messy.
feel free to change it and to make a better design.

I've also added default values of signatures & fixed arguments type when it served as an array, check for example => removeData.
