* Add `myouSetKeyboardVisible(bool)` and export it.
* Add `screen.char_callbacks` to receive platform character events.
* Remove duplicate code for mouse emulation with touch (commited by mistake).
* Incomplete port of myou-engine-js to nimskull, after many months of work, and
a few extra features that weren't exactly necessary for a "first commit" to
work. Excuse the lack of commit history up to this point.
* Bare bones structure of the documentation and the process to update it.
* Restructure of the whole project to have a more sensible organization.
* Making submodules of forks of larger libraries.
* README, licenses, AUTHORS.md.
