More Fluid.js changes...

[Colin Clark]

Hi all,

Just prior to code freeze, I made a few more changes to Fluid.js, all  
in the name of reducing our download footprint:

* The fluid.util namespace has been removed entirely. Any functions  
within it were deemed of such utility that they have been promoted to  
the top-level fluid namespace.

* fluid.formatFileSize() has been moved to  
fluid.Uploader.formatFileSize() inside Uploader.js

* fluid.roles, fluid.keys, and fluid.keysets have been moved into the  
fluid.reorderer namespace in Reorderer.js. Other components that need  
key constants should use the keyboard-a11y plugin instead.

* fluid.findKey has been renamed to fluid.findKeyInObject to better  
describe its purpose

* I've created a new JavaScript file called FluidDOMUtilities.js for  
pure DOM functions that provide optimized implementations in cases  
where working on jQueries is too slow. These are a rare bunch, and at  
the moment are only required by the Reordererd due to its performance  
requirements. These functions include:

fluid.dom.iterateDom
fluid.dom.computeAbsolutePosition
fluid.dom.isContainer
fluid.dom.insertAfter
fluid.dom.isWhitespaceNode
fluid.dom.isIgnorableNode
fluid.dom.cleanseScripts
fluid.dom.dumpEl

* I reorganized Fluid.js so related functions are grouped together in  
the file. This should make browsing through it a little easier. It's  
also been heavily lintified.

Renaming and relocating functions can be pretty challenging in  
JavaScript  without the benefit of refactoring tools. As far as I  
know, I've tested these changes with all our unit tests and sample  
code files, but please let me know if I've missed any.
