WIP: Add a simple website using mkdocs
Features:
- A simple website built automatically from Git, available at https://gnome.pages.gitlab.gnome.org/tracker-miners/
- An overview of Tracker and links to user documentation (related with tracker#97 and also provides a sort of work around for )
- Reference documentation built from Git and published at https://gnome.pages.gitlab.gnome.org/tracker/docs/api-preview (providing a semi-workaround for tracker#100)
Previously this was an MR against tracker.git, but in order to include all reference docs and manpages, it will need to be built as part of tracker-miners.
