/* 
	jQuery plugin to allow input fields to be emptied when they get focus and,
	if necessary, to restore the original content when the user doesn't enter anything.
	
	Parameters:
		- selector: an extra filter that will be applied on the input fields, limiting the ones that are cleared
					e.g. clearFields(selector: '.clean'); will only fire on inputfields that have class "clean"
		- textFields: true/false determines if text fields should be cleared. Default = true
		- textAreas: true/false determines if text areas should be cleared. Default = true
		- passwordFields: true/false determines if password fields should be cleared. Default = true
