Resolved "title" for all Foundations Slide Deck materials

This resolves both "title" placeholder in all Foundations slide Markdown, and the integration with HydeSlides Launcher.

* All Foundations slides in use now have meaningful title in filename
* "Title" attribute in front matter of Foundations slides now removed (in favor of one in filename)
* New support for `cover:false` and `heading:false` in front matter to hide any chapter cover or individual slide heading (i.e. slides with sticky notes, big diagrams, etc.)
* HydeSlide Launcher now parses out the Markdown's title based on the slide build-out, whether or not the title is shown/hidden.
