Script for generating EPUB 3 with braille rendition

[bertfrees]

To do:

• [ ] rethink how to do input-output synchronization
• [x] update cross-references
  • e.g. in SMIL files
  • e.g. link[@rel="next"]/@href
  • e.g. a[@epub:type="noteref"]/@href
• [ ] remove unreferenced files
• [x] add META-INF/metadata.xml
• [ ] add rendition:media to META-INF/container.xml
• [x] add rendition:layout to META-INF/container.xml
• [x] add rendition:language to META-INF/container.xml
  • e.g. copy the value of the dc:language in the Package Document and set script subtag to "Brai"
• [x] add rendition:accessMode to META-INF/container.xml
• [x] add rendition:label attributes to META-INF/container.xml
• [x] translate alt attributes
• [x] move rendition mapping XML to EPUB directory
• [x] move <dc:type>edupub</dc:type> to metadata.xml if present

Blocked on:

• [x] https://github.com/daisy/pipeline-modules-common/pull/73

On second thought, the 'resource-map' output port of XProcTransforms may not be such a good idea after all. To chain such steps is not trivial, and moreover it adds complexity to each step. A better approach would be to move the burden of computing the mapping to outside of the step (or chain of steps), and to limit the responsibility of the step itself to preserving synchronization points in the input. What these synchronization points should like should be specified in the XProcTransform contract.

Branch was moved to daisy/pipeline-mod-braille. There is also a rebased version braille-in-epub3-rebased that I did a while back.

Now I have rebased it again to sbs-ebraille. Note that this branch does not include the "resource-map" part yet which I want to re-implement.
