Description		: extension of the jQuery Object
Modifications	: 
	- added select chains management
	- fixed select chains (child select now fires event change after options remake)
	- fixed attachValidator (opt is now declared in the right way !!)
	- fixed detachValidator
	- added include on demand plugin
	- added enabled/disabled state to the activityBar
	- added $.string() prototype functions
	- added str_random(l): returns a random string of l characters
	- fixed visualization of the activityBar
	- modified function activityRemoveMessage(id): it is now possible to clear all messages (id='all')
	- deleted functions activityHide() and activityShow()
	- added masked input plugin
	- modified validation of dates (now 00/00/0000 dates are accepted)
	- added onParentChange parameter to selectChain()
