Fix the media-type of the navigation document.
zedai-to-epub3: Use the computed nav doc explicitly

Use the px:create-package-doc "nav-uri" option to force the nav doc
to declare in the the OPF to be the computed nav doc.
This prevents some conflicts if the HTML contains multiple toc navs.

Update dtbook-to-daisy3 to the new TTS workflow

- It is required to first merge the branch 'move-css' of pipeline-mod-tts.
- TTS options are now gathered in a config file.

Close #48
Translate @xml:lang in zedai-to-html
Support TTS MO in zedai-to-epub3 and dtbook-to-epub3

Still experimental regarding the configuration with CSS.
Requires 'assert-valid' to be set to false for most of the validations.
Move EPUB MO creation to mediaoverlay-utils
Flexible URI for the TTS config option
- Changed the type of the TTS config option to take advantage of the URI normalization
Remove useless import
Pass output dir URI to TTS modules

- must be synchronized with pipeline-mod-tts's remote-log branch
initial commit for epub3-to-daisy202

adapted from parts of the nordic-epub3-dtbook-migrator project:
https://github.com/josteinaj/nordic-epub3-dtbook-migrator
sample with smils, xprocspec test, improved xproc outline
a bunch of work on html5-to-html4.xsl; still some elements remaining
more work on html5-to-html4.xsl; most elements done; a few remaining
html5-to-html4: xslt and xspec finished. daisy202 sample added

the daisy202 sample should be equivalent to the epub3 sample and will be used for the xprocspec tests.
initial commit for a XProc/XSLT port of the Pipeline 1 DAISY 2.02 validator

More work on the EPUB3 to DAISY 2.02 converter made it clear that a DAISY 2.02 validator is very useful.
A DAISY 2.02 validator will be invoked after conversion to make sure the result is valid. The EPUB3 Validator (epubcheck)
will also be invoked before conversion to make sure the input is valid.

The port of the "Daisy 2.02 DTB Light Validator" is rudamentary and untested but it should run successfully.
The only thing it validates at the moment is that the SMIL clock values add up to the declared totalTime in the SMIL and NCC headers.
