Privacy and bot parsing update

Accidentally the last version has the ajax bit set, so google would never see jsonld data.
Also, change back to $child->canShow() instead of canShowName().

Compatiblity update for webtrees 1.7

This is a compatiblity update for Webtrees 1.7. Please remove the old modules_v3/jsonld-folder first befor deploying.

Added children, birth places, and fixed project setup.

v0.1.1 error fixes

Sorry for some dumb merging errors. Includes are fixed, image field from person is removed.

v0.1 - jsonld for webtrees 1.6.2

First release (v0.1) of jsonld for webtrees 1.6.2. It supports person, parents, birthDate and birthPlace (although not 100% properly). It requires PHP 5.4 due to json_encode()-options. Do not try on PHP 5.3.

If you find any bugs, please put them into the issue tracker.
