Create ImportTileset.csx

[AwfulNasty]

Description

Includes ImportTIleset script that works in the same way as ImportGraphics. Auto imports Tile IDs, a previously tedious process.

Caveats

It feels odd to have a script that functions the same way as ImportGraphics, but also able to do tilesets.

Notes

Maybe this script should be consolidated with ImportGraphics, but doing so would hide the change to people used to UMT. Cutting out the parts that import other assets might be best here?

what if everyone has write access on a repo like a wiki

You should undo the "Room Editor Creation Code Support" commit and create a separate PR with that commit only.

@AwfulNasty can you please change the PR to remove the unrelated commit?
