Add Tomb Raider I-III Remastered detection (#66)

Make controller.game detect the game directory called
"Tomb Raider I-III Remastered" for steam app ID 2478970. This game will
launch with the generic controller.mod, which is only tested implicitly
through tests for controller.bethesda.

I don't own this game so I haven't manually tested it.

If you have the file
`~/.local/share/ammo/Tomb\ Raider I\-III\ Remastered.json`
you will need to delete it or rename it in order for ammo to present the
automatically detected game rather than the game configured manually via
that file.
