Release pending

I had problems finding an editor for Nintendo Entertainment System (NES) CHR-roms for modern Macs, I ended up making one, rather than tinker with getting some of the otherwise excellent older windows editors to work on mac. 

CHREditor is pretty basic, but gets the job done. You can create new roms and edit existing rom files. It's possible to import and export palettes and of course edit the various tiles. And it even includes a best effort image import, that will let you import a png/jpg/gif/etc and convert it to tiles

Features:

- Open, edit, save CHR-roms

- Support multiple banks

- Image import

- Supports up to 4 palettes

- Define, import and export palettes

- Include QuickLook for Finder
