Organize Files

Files are now organized into subdirectories based on manufacturer/brand.
Where possible, files have been updated to a naming standard:
Example: "Brand_Model.ir"

These changes should allow for faster finding of necessary files, and
the naming standard should keep things fairly cohesive across the board.

This is a proposed change and I'm absolutely open to feedback to
make it better before merging- thanks!
