sc: bone eater preliminary support (#895)

## Link to GitHub Issue or related Pull Request, if one exists
Fixes #114

## Description of change
Initial support for Silent Scope: Bone Eater, enough to be playable;
doesn't include QoS work needed to make this a smoother experience.

* Game detection
* Fix DX11 overlay to work with non-Unity games
* Implements sub monitor i/o (only really needed to get past I/O check)
* Try to make the game reasonably playable with a mouse
* Ignore the game's attempt to move windows, position them in a
reasonable place
* Fix language hook
