Description		: 
	- function to check the response (XML formatted)
	- XML, boolean and string functions
	- form creation
Modifications	: 
	- added field swapping (show/hide) functionality to input[type=checkbox]
	- added date field
	- added new button for the form: 'Done'
	- added cancel_upload option to upload()
	- upload() and gallery() extradata can be functions
	- added maxlength options for input()
	- swapper field can execute functions (toshow and tohide)
	- fixed older calls to xml_* functions
	- fixed select(): it can be chainable even if no items are supplied
	- fixed collectField(): <br /> cut out from textareas
