Code review request for FLUID-4235

[Michelle D'Souza]

Hi,

I've been working on the creating and storing a page enhancer in the static environment. This change removes the antiquated use of jquery.data for storing the UIEnhancer that UIOptions depends on for doing page level changes based on user settings. I'm at a point where some code review would be great. 

This is my branch where I've been doing lots of little commits:
https://github.com/michelled/infusion/commits/FLUID-4235

The changes that you'll see are:

	* the pageEnhancer was created
	* the UIEnhancer API has changed from (document, options) to (container, options)
	* the 'onSave' event was removed from UIEnhancer
	* most of UIOptions' dependence on the UIEnhancer was removed - there is still one use of the uiEnhancer applier in the save function

Thanks,

Michelle
