Re-added AUIRenderer.java
added changes so that components can be rendered at the bottom of the page with only one AUI.use. Also consolidated some javascript response writing into AUIRenderer class instead of child classes
regenerated all components to use AUIRenderer beginJavaScript and endJavaScript methods, plus a handleBuffer method to optimize the javascript when we are not in an ajax request
added getModule() abstract method which child renderers shoudl implement to tell the parent wich module to use
fixed typo in generator.properties
regen using getModule() method in renderers
Generator now reading properties from generator.properties instead of system properties
Regenerate
Adding default renderers
