	jQuery plugin placeholder by Jakob Givoni
	
	PURPOSE:
	- Immitates attribute placeholder as it works in Chrome, Opera etc.
	- Helps the user easily identify input fields and what to type in them.
	- Visual hint: Prefills your input or textarea field with the value of your title attribute (the tooltip becomes the initial value)
	- Removes the hint on focus
	- Reenters the hint on blur of field is left empty
	- Styling: Adds a class when the field contains the placeholder text. Use it to i.e. style the text dimmed, lightening the color
	- Hint not submitted: Removes the name attribute while the hint is displayed so that the hint won't be submitted if case of form submission
	
	USAGE:
	jQuery('input').placeholder(options); // options is an optional object
	- optional options: 
		- activeClass: the class name to add when the field is showing the hint (ie when the field is empty and not focused)
