Integrated ReadiumSDK renderer into the Readium.js project; all previous rendering code (epub-reader, epub-fixed and epub-reflowable modules) have been removed; the epub-parser and epub module have been merged; requirejs and some of the byte-range code has also been integrated; the developer's sample application has been updated to reflect changes. This commit marks a major change in the design and implementation of Readium.js. The independent components of Readium.js now provide a wrapper around the javascript 'rendering' components of the ReadiumSDK project.
