Support for up to 32 simultaneous colors

Fixed in 710664d. It does the palette fixing for you but it does do it silently.

Selecting two palettes and assigning one per tile is a much more tricky problem than bmp2tile solves right now. It could try to detect if the image is already suitably divided into 8x8 blocks of matching palettes, I suppose.

I understand. The worst part is to select which of the 32 colors should be on which of the 2 palettes.

But it will be easier if you add the requisite that the artist must have worked with two separate palettes himself.

Then, to populate the palettes on the conversion, you just would have a preliminary step to group the 32 colors as they appear together on the file. Scan tile for tile, then create the two color tables separately, both ordered from the most used color to the least used.

If one of the tables ends up with more than 32 colors, you can issue a warning and:

1. Move the excessive least used colors from one table to the other
2. Change the offending pixel of that tile to the closest color in the palette that tile uses

Not perfect, but better than nothing. :)

This would be very handy. I suppose while loading the image it could detect that and ask the user if he wants to continue in dual-palette mode, where tiles would work as expected, tilemaps would use the palette bit according to image and palettes would export a 'dual palette' (32 bytes for SMS).
