Update to v106r2 release.

Changelog:

  - Super Famicom: added support for loading manifests without embedded
    mapping information¹
  - genius: initial commit
  - various Makefile cleanups

¹: so the idea here is to try and aim for a stable manifest format,
and to allow direct transposition of icarus/genius database entries into
manifest files. The exact mechanics of how this is going to work is
currently in flux, but we'll get there.

For right now, `Super Famicom.sys` gains `boards.bml`, which is the raw
database from my board-editor tool, and higan itself tries to load
`boards.bml`, match an entry to game/board from the game's `manifest.bml`
file, and then transform it into the format currently used by higan. It
does this only when the game's `manifest.bml` file lacks a board node.
When such a board node exists, it works as previous versions of higan
did.

The only incompatible change right now is information/title is now
located at game/label. I may transition window title display to just use
the filenames instead.

Longer term, some thought is going to need to go into the format of the
`boards.bml` database itself, and at which point in the process I should
be transforming things.

Give it time, we'll refine this into something nicer.
