Experimental reorganization of modules and APIs to employ RequireJS/AMD
(Asynchronous Module Definition) with radical simplification of the
project's build system.

Note that some third party libraries that use browser globals are still
loaded in a classical way, using SCRIPT tags before the require.js tag.

Also includes changes from the experimental support for HTTP byte range
fetching from zipped EPUBs.

Add missing dependencies between RequireJS modules.
Add dependencies between Rake builds of different epub modules.
Simplify samples project Rakefile and make its build dependent on builds of epub
modules.
Eliminate directory prefix from RequireJS epub module names. Use built
minified versions of modules in the sample test application.
Fix a race condition with asynchronous loading of test site's event
handling script.

Reorganization of epub JS modules and build system for RequireJS/AMD, support for remote zipped EPUB files using partial HTTP fetching
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.
Move the readium-shared-js submodule to adhere to the structure assumed
for all modules - note that the submodule needs to be reinitialized in
your working copy.

Fixed bugs with incorrect initialization of epub-fetch and ReadiumSDK
reader view;
Reorganized epub modules directory structure - moved the epub-renderer
module to a subdirectory so that it adheres to the structure assumed for
other modules - note that the readium-shared-js submodule has also moved
and needs to be reinitialized in your working copy;
Implemented single file versions of the Readium JS library in 4 variants
(AMD and synchronous loading; minified and non-minified);
Updated the sample test site to use the single file, AMD loaded version
of the Readium library instead of using the separate epub modules
manually.

Switch the readium-shared-js submodule to point to the current tip
commit of the feature/renderer_improvements branch as it contains
critical rendering bugfixes. Rebuild the resulting Readium library
files.
