Replaced transformation functions, etc.

Browse Source 
charTransformation, textTransformation, and backTransformation have been replaced with a single `transformation()` function that takes five arguments and spits out three.
```
win.meta.transformation(x, y, char, text, back, meta)
    return {newCharX, newCharY, newChar}, {newTextX, newTextY, newTextCol}, {newBackX, newBackY, newBackCol}
end
```
