Elimination of SMIL parser's dependency on readium-js specific data.

The SMIL parser no longer makes use of the readium-js - specific
package document JSON data structure.
Remove unused jQuery module dependency declarations
Remove unused isFixedLayout method, inline the getMediaOverlay function
Removal of page progression direction info from readium-js JSON metadata
Rename the PackageDocument.getPackageData() method to getSharedJsPackageData()

The new name reflects the fact that the method should return JSON data
structure expected by readium-shared-js.
Removal of Jasmine tests leftover from Readium-Web-Components.

The tests have been made against the old, unsupported behaviour of
the module that was in place before readium-shared-js integration.
Remove the redundant epub-modules/epub/lib directory.

This directory has been made redundant a long time ago with the
introduction of Grunt-based builds.

Elimination of remaining endemic data structures.

readium-shared-js are produced and used.
